01 — StoryAbout me

September 19, 2026.

I started a company while I was in university. I was 20. It did not go well, but I have used the methods I learned then to add what I can do, one thing at a time.

I thought that if I used the management systems I learned from running a company for my own growth, the results could be remarkable. After putting the company on hold, I built a system for my own growth and have been putting it into practice.

What I want is work that only I can do. Art, English, basketball, technology. Each one alone is not rare, but by combining them I am building a field of my own.

From there, I want to bring many things into the world. This site is the record along the way.
