The Hard Truth No One Tells You

You finally gathered the courage to start that side hustle. You shared your dream with colleagues over lunch. Their response?

“Oh, nice hobby. But be careful – my cousin tried that and failed.”
“Stick to your job – at least it’s stable.”
“Who’s going to buy from YOU?”

Suddenly, your excitement feels foolish. The first month passes with just ₹3,000 in earnings. Your spouse asks, “Is this really worth your time?”

This is where 95% of dreams die – not from lack of potential, but from the unbearable weight of early struggles.

Starting a new venture or side hustle is an exciting journey – but it’s also one filled with unseen challenges that can shake your confidence and test your patience. If you’ve ever felt discouraged by slow progress, skeptical peers, or early setbacks, you’re not alone. These are common experiences that every entrepreneur or hustler faces, and understanding them is key to pushing through.

The Hidden Battle: Low Self-Esteem and Negative Criticism

Low self-esteem is among the first obstacles. When you present your dream to colleagues, friends, or family members, you could be met with doubts or negative criticism. These kinds of conversations tend to seed doubts. For instance, most startup entrepreneurs are initially faced with such doubts.

It’s all part of the process. Self-confidence isn’t achieved immediately; it gains momentum over a period of time as you rack up little wins. Experts suggest starting slowly, starting with areas where you already have skills and experience to build a foundation of success.

The Pressure of Balancing Responsibilities

As you build your side business, you juggle official employment, family, and personal life. No one else in your vicinity will even notice the extra hours that you put in. This invisibility makes it even harder to defend the work, leaving you more inclined to quit. The trick is to remind yourself that your dream entails sacrifices that others do not value.

How to Carry On When You Feel Like Giving Up

• Work in Silence, Let Results Speak: Do not boast about every difficulty. Concentrate on persistent effort as opposed to instant reward.
• Set Realistic Expectations: Realize that every company takes time to mature. Do not anticipate overnight success.
• Build Confidence Gradually: Begin with small, achievable goals in your areas of strength. Mark milestones to provide an uplift to morale[4].
• Obtain Mentorship and Encouragement: It is not excessive to consult with successful entrepreneurs or online communities even if the first few tries are rejected[3].
• Plan in Advance: Prepare a business plan with your targets, marketing, finances, and schedules. Planning minimizes uncertainty and prepares you for problems[6].

Why You Have to Keep Trying

If you choose to give up when things get difficult, your dreams will be nothing more than dreams. To live life beyond the ordinary, you must be willing to do what others will not: persevere through the quiet struggle. Remember, every successful entrepreneur has experienced failure and disappointment. What sets them apart is their determination to keep moving forward in spite of these failures.

The Life-Changing Perspective Shift

Every late night, every ignored insult, every failed attempt is:
→ Depositing into your future freedom account
→ Writing the “how I made it” story your kids will tell
→ Building the unshakable confidence that comes only from overcoming doubt

This struggle isn’t your obstacle – it’s your unfair advantage. Those who quit never develop the resilience your journey is forcing you to build.

Final Rally Cry:
“When you’re tempted to quit, remember: The version of you that survives this grind will laugh at what once seemed impossible. Keep going – your future self is counting on you.”

P.S. Feeling stuck right now? Do this:

1. Grab paper → Write today’s date + “I WILL NOT QUIT”
2. List 3 micro-actions for this week (e.g., “Post 1 Reel,” “Email 5 clients”)
3. Put it where you’ll see it daily (bathroom mirror/wallet)

Machine learning has become a powerful tool for predicting stock prices, as it allows for the analysis of large amounts of data and can identify patterns that humans may not be able to discern. In this blog post, we’ll explore how machine learning is used to predict stock prices and some of the challenges that come with this approach.

Time series forecasting

One of the most popular methods for predicting stock prices using machine learning is called “time series forecasting.” This approach involves using historical data on stock prices, such as daily closing prices, to train a model that can then be used to make predictions about future stock prices. The model looks at patterns in the historical data, such as trends and seasonality, to make predictions about future prices.

Sentiment analysis

Another popular method is called “sentiment analysis,” which uses natural language processing (NLP) to analyze news articles, social media posts, and other text data to determine the overall sentiment or tone of the market. The idea is that if the sentiment is positive, the market will likely go up, and if the sentiment is negative, the market will likely go down.

Dynamic nature and complexity of the stock market

One of the challenges with using machine learning to predict stock prices is that the stock market is highly dynamic and constantly changing. This means that models need to be constantly retrained and updated to take into account new data and changing market conditions. Additionally, it is hard to get accurate data and feature engineering is crucial for the model performance.

Another challenge is the complexity of the stock market itself, with many factors impacting stock prices such as company performance, economic indicators, and global events. This means that a machine learning model may not be able to take all of these factors into account and may produce inaccurate predictions as a result.

Machine learning algorithms to predict stock prices

There is no single machine learning algorithm that is guaranteed to provide the most accurate predictions of stock prices. The best algorithm depends on the specific characteristics of the data, such as the time period being analyzed and the presence of any specific trends. That being said, some of the more commonly used machine learning algorithms for stock price prediction include:

1. Artificial Neural Networks (ANNs) – ANNs are used to model complex relationships between inputs and outputs, making them well-suited for stock price prediction.
2. Support Vector Machines (SVMs) – SVMs are used for classification and regression tasks, and have been applied to stock price prediction to identify trends and make predictions based on historical data.
3. Decision Trees and Random Forests – Decision trees and random forests are used for classification and regression tasks, and can be applied to stock price prediction by analyzing the relationships between stock prices and a variety of factors, such as economic indicators, company-specific news and events, and global events.
4. Time series analysis (ARIMA, SARIMA, etc.) – Time series analysis methods are used to model time-dependent data, and are often applied to stock price prediction by analyzing trends and patterns in historical stock data.

Regardless of the algorithm used, it is important to have a solid understanding of the stock market and to thoroughly validate and test the model before using it to make any investment decisions.

Irreplaceable human judgement and knowledge

Despite these challenges, machine learning has the potential to revolutionize the way we predict stock prices. With the increasing availability of data and advances in machine learning techniques, it’s likely that we’ll see more and more accurate predictions in the future. However, it is important to note that stock prices are highly unpredictable and machine learning should be used as one of the tools in the decision making process.

Stock trading with AI algorithms

Algo trading is very popular nowadays amongst systematic traders. They just hand over the decision-making process to a few pieces of code and sit back. The backtested code runs on some logic set by the trader with a certain probability of profitability.

So, why not take the advantage of Machine Learning to develop a concrete trading system with a higher winning percentage?

Trading with machine learning typically involves using algorithms to analyze large amounts of historical market data, identify patterns and trends, and make predictions about future price movements. These predictions can then be used to inform trading decisions, such as when to buy or sell a particular security.

However, it’s important to note that even the most sophisticated machine learning algorithms cannot guarantee profits and carry significant risks. A well-designed machine learning model should be validated and tested thoroughly on historical data before being used to make investment decisions. It’s also important to be aware of the limitations of machine learning algorithms and to use them in conjunction with other forms of analysis, such as fundamental analysis and technical analysis.

Final words

Machine learning has become a powerful tool for predicting stock prices, with time series forecasting and sentiment analysis being two of the most popular methods. While there are challenges that come with using machine learning in this context, such as the dynamic nature of the stock market and the complexity of the factors that impact stock prices, advances in machine learning techniques have the potential to lead to more accurate predictions in the future. As always, it’s important to use a variety of tools and approaches to make investment decisions, and not to rely solely on machine learning predictions.

Machine learning is a rapidly growing field that is changing the way we interact with technology. It is a method of teaching computers to learn from data, without explicitly programming them. This allows computers to identify patterns and make predictions, making it a powerful tool for solving complex problems.

If you’re new to machine learning, it can be overwhelming to know where to start. In this article, we will provide a beginner’s guide to machine learning, covering the basics and providing an overview of the most common techniques.

Supervised and unsupervised learning

First, it’s important to understand the difference between supervised and unsupervised learning. Supervised learning is when the computer is provided with labeled data, which means that the correct output is already known. This type of learning is used for tasks such as image classification, where the computer is shown an image and must identify what is in the image.

Unsupervised learning, on the other hand, is when the computer is not provided with labeled data. Instead, it must identify patterns and relationships within the data on its own. This type of learning is used for tasks such as clustering, where the computer groups similar data together.

Overfitting of models

Another important concept in machine learning is overfitting. This occurs when a model is too complex and performs well on the training data but poorly on new, unseen data. To prevent overfitting, it’s important to use techniques such as cross-validation and regularization.

Important machine learning algorithms

There are several popular machine learning algorithms that are commonly used, including:

Linear regression: used for predicting a continuous outcome

Linear regression is a supervised machine learning algorithm used for predicting a continuous outcome. The goal of linear regression is to find the best linear relationship between the input variables (also known as independent variables or predictors) and the output variable (also known as the dependent variable or target). It does this by finding the line of best fit, represented by the equation:

y=b₀+b₁x₂+….+b_n*x_n

Where y is the predicted value, x₁, x₂, …, x_n are the input variables, and b₀, b₁, b₂, …, b_n are the coefficients that need to be learned. These coefficients are learned by minimizing the difference between the predicted values and the true values.

Linear regression is a simple and interpretable algorithm that makes it easy to understand the relationship between the input variables and the output variable. However, it has some limitations, such as the assumption that the relationship between the variables is linear, which may not always be the case. In such situations, more complex algorithms such as polynomial regression or non-linear regression may be used.

Linear regression can be implemented in various programming languages such as Python, R, and Matlab. The most popular libraries for implementing Linear Regression are scikit-learn, statsmodels and tensorflow.

In summary, Linear Regression is a basic yet powerful algorithm for predicting a continuous outcome, it is easy to implement and interpret, and it is widely used in various fields such as finance, economics, and engineering.

Logistic regression: used for predicting a binary outcome

Logistic regression is a supervised machine learning algorithm used for predicting a binary outcome. It is a variation of linear regression, where the goal is to model the probability of a certain class or event occurring. The logistic function (also called the sigmoid function) is used to map the input variables to a probability between 0 and 1. This function is represented by the equation:

p(x) = 1 / (1 + e^-(b₀ + b₁x₁ + b₂x₂ + … + b_n*x_n))

Where x₁, x₂, …, x_n are the input variables, b₀, b₁, b₂, …, b_n are the coefficients that need to be learned, and p(x) is the predicted probability of the event occurring.

The logistic regression algorithm uses the logistic function to estimate the probability of the event occurring and uses a threshold (usually 0.5) to classify the outcome as either 0 or 1.

Logistic regression is a widely used algorithm for classification problems, it is easy to implement and interpret, and it can handle both linear and non-linear relationships between the input variables and the output variable. However, it has some limitations, such as the assumption that the relationship between the variables is log-linear, which may not always be the case. In such situations, more complex algorithms such as decision trees or support vector machines may be used.

Logistic regression can be implemented in various programming languages such as Python, R, and Matlab. The most popular libraries for implementing Logistic Regression are scikit-learn, statsmodels and tensorflow..

In summary: Logistic Regression is a powerful algorithm for predicting a binary outcome, it is easy to implement and interpret, and it is widely used in various fields such as medicine, finance and social sciences.

Decision trees: used for both classification and regression tasks

Decision Trees is a supervised machine learning algorithm used for both classification and regression tasks. It is a tree-based model where each internal node represents a test on an attribute, each branch represents the outcome of a test, and each leaf node represents a class label.

The idea behind decision trees is to recursively partition the data into subsets based on the values of the input features. The algorithm starts at the root node and selects the feature that best splits the data into subsets with the most similar class labels. The process is repeated on each subset of the data until a stopping criterion is met. The final result is a tree of decisions that can be used to make predictions for new data.

One of the main advantages of decision trees is their interpretability. They are easy to understand and visualize, and they can handle both categorical and numerical features. However, decision trees can be prone to overfitting, especially when the tree becomes too deep. This can be addressed by using techniques such as pruning, which removes branches that do not add much value to the tree.

Another popular variation of decision trees is random forests, which is an ensemble of decision trees. Random forests use multiple decision trees and combine their predictions to improve the overall performance of the model.

Decision Trees can be implemented in various programming languages such as Python, R, and Matlab. The most popular libraries for implementing Decision Trees are scikit-learn, R’s rpart package, and caret package.

In summary: Decision Trees is a powerful algorithm for both classification and regression tasks, it is easy to interpret and understand, it can handle both categorical and numerical features but can be prone to overfitting. The Random Forest is an ensemble of Decision Trees, which improve the overall performance of the model.

Random forests: an ensemble of decision trees

Random Forest is an ensemble machine learning algorithm used for both classification and regression tasks. It is a variation of decision trees, where multiple decision trees are trained and combined to make predictions. The idea behind random forests is to reduce the variance and increase the accuracy of the model by averaging the predictions of multiple decision trees.

A random forest algorithm generates multiple decision trees by training them on different subsets of the data. This is done by randomly selecting a subset of the features and a subset of the data points to use for each tree. The final prediction is made by averaging the predictions of all the trees in the forest.

One of the main advantages of random forests is that they are less prone to overfitting than single decision trees. This is because each tree in the forest is trained on a different subset of the data, which reduces the correlation between the trees. Additionally, random forests can handle both categorical and numerical features and are able to capture non-linear interactions between the features.

Random Forest can be implemented in various programming languages such as Python, R, and Matlab. The most popular libraries for implementing Random Forest are scikit-learn, R’s randomForest package, and caret package.

In summary: Random Forest is a powerful ensemble machine learning algorithm used for both classification and regression tasks, it’s less prone to overfitting than single decision trees, it can handle both categorical and numerical features and is able to capture non-linear interactions between the features. It combines the predictions of multiple decision trees to improve the overall performance of the model.

k-nearest neighbors: used for classification and regression tasks

k-nearest neighbors (k-NN) is a supervised machine learning algorithm used for both classification and regression tasks. It is a non-parametric method, which means that it does not make any assumptions about the underlying distribution of the data.

The idea behind k-NN is to classify a new point based on its similarity to other points in the data. The algorithm works by finding the k-nearest data points to the new point, and then the majority class or the average value of the k-nearest points is used to make the prediction.

One of the main advantages of k-NN is its simplicity and interpretability. It requires very little training data and can handle both categorical and numerical features. However, it can be sensitive to the choice of k and to the scale and distribution of the data. To overcome these issues, techniques such as normalization and feature scaling are often used.

The k-NN algorithm can be implemented in various programming languages such as Python, R, and Matlab. The most popular libraries for implementing k-NN are scikit-learn, R’s class and caret package.

In summary: k-nearest neighbors (k-NN) is a simple and interpretable algorithm used for both classification and regression tasks. It classifies a new point based on its similarity to other points in the data. It has the advantage of requiring very little training data and can handle both categorical and numerical features. However, it can be sensitive to the choice of k and to the scale and distribution of the data.

Support vector machines: used for classification tasks

Support Vector Machines (SVMs) is a supervised machine learning algorithm used for classification tasks. It is a powerful and versatile algorithm that can handle both linear and non-linear data.

The goal of an SVM is to find the best boundary (also called a hyperplane) that separates the data points into different classes. The boundary that maximizes the margin, which is the distance between the boundary and the closest data points from each class, is chosen as the best boundary. These closest data points from each class are called support vectors.

SVMs can handle both linear and non-linear data by using a technique called the kernel trick. The kernel trick transforms the input data into a higher-dimensional space where the data becomes linearly separable. In this new space, the algorithm finds the best boundary, and then it is transformed back to the original space.

One of the main advantages of SVMs is that they can handle high-dimensional data and have a high accuracy. However, they can be sensitive to the choice of the kernel and the parameters of the model. Additionally, SVMs can be less efficient with large datasets.

SVMs can be implemented in various programming languages such as Python, R, and Matlab. The most popular libraries for implementing SVMs are scikit-learn, R’s e1071 package, and MATLAB’s fitcsvm.

In summary: Support Vector Machines (SVMs) is a powerful and versatile algorithm used for classification tasks. It finds the best boundary that separates the data points into different classes, maximizing the margin. It can handle both linear and non-linear data using the kernel trick. SVMs have a high accuracy, but they can be sensitive to the choice of the kernel and the parameters of the model, and they can be less efficient with large datasets.

Neural networks: used for a wide range of tasks

Neural Networks (NNs) are a type of machine learning algorithm inspired by the structure and function of the human brain. They are a set of algorithms that are designed to recognize patterns in data, by learning from examples.

A neural network is made up of layers of interconnected nodes, also known as artificial neurons. Each neuron receives inputs, performs a computation on them, and then produces an output. The layers of neurons are connected to each other, and the output of one layer becomes the input for the next layer. The last layer produces the final output of the network.

The most common type of neural network is the feedforward neural network, also known as the multi-layer perceptron (MLP). In this type of network, the information flows only in one direction, from the input layer to the output layer.

There are other types of neural networks, such as recurrent neural networks (RNNs) and convolutional neural networks (CNNs), which are suited for specific tasks such as natural language processing and image recognition.

One of the main advantages of neural networks is their ability to learn complex, non-linear relationships in the data. They can be trained to perform a wide range of tasks, from simple linear regression to complex image recognition. However, neural networks can be difficult to train and can require a large amount of data and computational resources. Additionally, the process of understanding and interpreting the internal workings of a neural network can be challenging.

Neural networks can be implemented in various programming languages such as Python, R, and Matlab. The most popular libraries for implementing neural networks are TensorFlow, Keras, and PyTorch.

In summary: Neural Networks (NNs) are a type of machine learning algorithm inspired by the structure and function of the human brain. They are designed to recognize patterns in data, by learning from examples. They can be trained to perform a wide range of tasks, from simple linear regression to complex image recognition. They can be difficult to train and can require a large amount of data and computational resources, but they can learn complex, non-linear relationships in the data.

Conclusion

Finally, it’s important to understand the role of feature engineering in machine learning. This is the process of transforming raw data into useful inputs for a model. Feature engineering can greatly improve the performance of a model, so it’s an important step in any machine learning project.
