Are You Refusing to Quit Academics?

I'm sure there have been things that you may have regretted quitting at some point in your life. But the upside is that you probably learn something valuable about your own decision making process and how to improve it. So do you mind just sharing any regret you have about something you quit, but what you learn from that experience? You know, i so, so i actually, i actually regret quitting academics in the first place.
