Steve Levitt pushes this point, did some experiments around it: https://bfi.uchicago.edu/news/to-quit-force-a-moment-of-trut...

I donno, I've come across or read about fair number of people who worked on a crazy idea for a very long time, as if they were planning to throw their life away chasing that idea. Some had a breakthrough and ended up being a huge win. But I'm sure there are many many more who just ended up nowhere. So, I guess it's a gamble.

If you persist and win, they'll write good things about you. If you lose, they'll say you were stubborn.

Problem is that you never know if you are on a dead-end. It is something you can only know in retrospect and even then only sometimes

Advice is situational. Some people need to hear "don't give up" and some people need to hear "move on".

"Winners never quit and quitters never win, but those who never win and never quit are idiots"

This advice seems especially interesting because replit has certainly pivoted, so in that sense they kind of did quit?

you might be taking “quit” a little too literally :)

But how would you know when you've gotten to that point of trying something else?
