Mojito island (FIRE) is a mirage (2009)

If you've made enough money to live comfortably, I refute the notion that I need to hustle for more.

Instead, that would provide me the freedom to learn more, study more, create more, without having to care about the mundane stuff like having a home, food, water, etc.

If that business really is a new passion, go for it. If it's just because you're bored, consider just doing the thing you like without the business side. Perhaps if you really want to make software that fills a gap somewhere, release it open-source. Be different from the average grifter, if you dare.
