Me! I started my solo, startup law practice almost by accident via a Hacker News comment years ago. It's now my primary source of income.

It's hard, but less hard than what startup founders do. It's nice having control of my schedule, but the flip side is that there's never a day off. Personally, I think being self-employed is great for people who naturally work really hard and want to capture the full output of their labor.

I don't think I could ever go back to full time employment for someone else. It's addicting having your own business that actually cash flows!
