(2025) Creating a Profitable MBTI Test-Based Website - <Let's Learn Coding and Start a Business>

How to monetize my website? 🤔

"If you don't find a way to make money while you sleep, you will work until you die."
This is a famous quote by Warren Buffett. This also applies to those who program.

In this course, we will build a content-based website optimized for monetization ourselves. Many of you may have started learning development because it was fun or to get a job, but at some point, it might have turned into studying just for the sake of studying, leading to feelings of boredom.

Through this course, let's build a website for generating revenue right away. Experience for yourself that a good service isn't about the difficulty of development, and that you can generate plenty of profit while creating your own service that users enjoy!

I cannot promise that you will automatically generate revenue just by taking this course.

However, by taking this course, you can learn how to use weapons that make money for you.

Of course, there is no such thing as 100%. Anyone who says you can unconditionally make money is either a scammer or just deluding themselves.

But you can increase the probability of success.

Launch fast, validate fast, and monetize fast

This is the attitude we must adopt in an era where even major IT corporations are laying off developers.

And the first step to increasing the odds is 'trying quickly'.

Through this course, we will quickly build and launch a service to validate its profitability.

And you might fail. That is why we intend to start and verify with as close to zero cost as possible.

Through these multiple attempts, we will learn new things and increase our chances of success.

Labor income is important, but we have entered an era where we cannot rely solely on it. It is a time when we need to attempt to survive in capitalism on our own by creating our own services.

We are creating a service like this

✨ In the 21st century, we live in an era where traffic equals profit.
And that traffic naturally gravitates toward those with compelling content.

On YouTube, blogs, and Instagram, so many people strive to generate revenue with an overwhelming amount of content. However, as competition intensifies, it becomes harder to establish your own competitive edge, and many end up quitting after a week of effort, thinking, "Maybe this isn't for me."

💡What if you personally created and operated an attractive service that others have rarely attempted?
Solo developers (Indie Hackers) are people who travel the world with just a laptop, earning anywhere from several thousand to tens of thousands of dollars a month on their own. Pieter Levels is the most representative indie hacker (I highly recommend looking him up).

The characteristics and strengths of these successful indie hackers vary, but they all share one thing in common.

Execute fast, experiment fast, and get feedback fast

These are people who prove through their lives the proposition that time is money. If they have an idea, they build it quickly without overthinking, launch it to the market fast, and then receive feedback quickly to make rapid improvements.

It doesn't matter if they fail. This is because they have significantly reduced risk by starting with zero costs through their own coding know-how. Failed attempts instead become part of their portfolio and serve as the nourishment they need to learn for future success.

👍 I hope you will step into the fascinating world of profitable programming with <Learn Coding to Invest: LCI>.
Since 2020, I have incorporated my know-how as an indie hacker for <Fast Execution/Experimentation/Feedback>, gained through repeated failures and successes while trying various services.

In this course, while coding-related content forms the framework for creating a finished product, I have infused it with the underlying know-how for operating a profitable website, so I hope you enjoy it to the fullest.

Features of this course

📌 We focus on the content necessary for practical site construction and monetization, rather than technology for technology's sake.

📌 This is not just a follow-along lecture; we code while thinking together about monetization strategies.

📌 Unless it is unavoidable, we will utilize free infrastructure as much as possible to keep costs low.

📌 Sharing source code is standard. The course is updated whenever better monetization strategies are developed.
