If I look at the last 15 years of knowing people in startups, and then seeing who became successful and who didn't, I'm starting to see some general patterns
The people I know who became successful (and very rich) regularly asked for help and feedback, and then applied that feedback very quickly (think minutes) and shipped fast while maintaining their own vision
The people who didn't become successful are the ones who worked on stuff for months/years without asking for help or feedback, or when they did took weeks/months to apply it
So I think the feedback -> implement loop and speed of it is possibly very important
