Recently, I’ve increasingly felt that the ultimate secret of life might be compound interest.
Not compound interest in the financial sense, but the compound interest a person accumulates bit by bit every day in their life, learning, body, expression, and career.
I used to think that success was brought about by a crucial opportunity, an outburst, or a sudden turning point. But recently, looking at some examples around me and on the internet, I’ve begun to realize that many so-called “sudden successes” didn’t actually happen suddenly.
Let me share two stories:
The First Story
I have a former colleague who loves working out. Since last year, he has been sharing his training process on social media.
At first, I saw it a few times, but it seems I forgot to follow him, so I didn’t see his updates every day. Until a few days ago, I stumbled upon a post again. The person in it looked very familiar—looking closely, hey, isn’t that him? Then I clicked in and found that he already had thousands of followers. I was a bit shocked and went back through his records. I found that he had been consistently working out and posting. The content was actually very simple: a selfie after each workout, similar to a Live Photo. There were no flashy edits, no chicken-soup captions. But you could visibly see: his physique was getting better bit by bit, and the number of likes grew from just a few to hundreds. This really moved me. What truly shocked me was not that he gained thousands of followers. Because gaining thousands of followers inherently involves two completely different situations.
The first is suddenly gaining thousands of followers in a short period of time.
This is of course also very impressive; behind it, there might be marketing skills, trending topics, platform recommendations, content operations, and various other factors. When I see this situation, my reaction is usually:
“Wow, this person is really amazing.”
But this shock comes more from the result itself.
The second type: like my former colleague.
There was no complex operational strategy, nor any viral content. He just worked out every day. Posted when he trained chest, posted when he trained shoulders, posted when he trained legs. Occasionally recorded weight changes, occasionally posted a post-workout photo.
The content was extremely ordinary.
Except for the act of “consistently working out” itself, everything in this story was very simple.
Simple things are easy to repeat for a day. Repeating them for a year is not simple.
At this point, the feeling it gave me was no longer “this person is really amazing.” Instead, it was:
“So it turns out, this is also possible.”
Because you can clearly see that the growth in followers is just the result. What truly changed was actually himself. Over this year:
- His physique got better
- His training experience became richer
- The habit of documenting was formed
Followers are just a bonus. Growth is the main product.
There were no shortcuts in this process. No outbursts, no luck, no sudden miracles.
There was only recording a little bit every day, making progress a little bit every day.
Then, when looking back at a certain point in time, you find that these seemingly insignificant small actions have accumulated into quite a considerable result. This is perhaps the most fascinating part of compound interest. It won’t give you feedback on the first day. It won’t give you feedback on the tenth day. It won’t even give you feedback on the thirtieth day. But when the time is long enough, it will magnify all your seemingly unnoticeable persistence.
The Second Story
The second story is about BridgeMind on YouTube. He started consistently streaming vibe coding over 180 days ago, with the goal of making $1 million through this method. More than 180 days later, he has accumulated over 70,000 followers on YouTube, and the Annual Recurring Revenue (ARR) of his product has also exceeded $200,000.
But what I find more interesting is not just the result, but that he witnessed a period of extremely rapid change.
In less than a year, AI tools have iterated at a ridiculous speed: From the initial era of Cursor and Windsurf to the current era of Claude Code and Codex. Although it has only been a short nine months, in the AI world, that is a world of difference.
To be honest, whenever a new AI model comes out, my first reaction is not to look at the official documents, but to watch his videos. I want to see how he uses it in a real vibe coding scenario, and whether this model is really as strong as the benchmarks say.
Similarly, compound interest also has different levels.
My former colleague who works out showed me: Persistently doing the right thing over a long period will generate compound interest by itself.
And BridgeMind showed me: If you can persist over a long period in a direction of rapid growth, compound interest will also superimpose the amplifying effect of the trend.
One is the compound interest of time. The other is the compound interest of time × trend.
Many people are always looking for shortcuts.
But looking back—whether it’s working out or BridgeMind, what they did wasn’t actually complicated.
What is truly complicated is:
- Continuing to do it when others can’t see the results
- Continuing to record when there is no applause
- Continuing to accumulate when there is no return
When the time is long enough, Compound interest will naturally speak for you.
Speaking of myself.
Recently, I’ve been looking for a job in Japan. As a foreigner, the language barrier is truly difficult.
But I’ve started trying to break down what I need to prepare every day into small pieces. Breaking the ultimate goal into small pieces too.
Overcoming a little every day, practicing a little every day.
Letting compound interest help me.
I believe in compound interest.
Even if the final result is not as expected—by doing what I need to do every day, I have already won.
