I struggled 10 years to find a SaaS product that worked, launched 20 projects (and there was no AI back then), way before the "indie hackers" movement.

Now our company is doing a few millions a year, highly profitable, no VC or external investment.

Was luck that I decided to try over and over? I might got lucky, but I persisted for so long while many others gave up. For me, making your own luck fits very well. Working hard gives you opportunities and you learn in the process so on next try, chances are better. Last projects got more and more profitable as I learned how to identify what people want.
