Don't sell your house if you don't have a realistic place to live lined up. Don't divorce your wife if it's not worth the work.
I'm not saying everyone can or should be grindset hustle bro. Probably no one. I'm just saying that it is sometimes possible to decide what you're going to do in advance. If you already have too many obligations, that could include deciding which ones to fail. That's probably better than trying to do everything and just rolling the dice.
It's surprising how controversial this idea is, but it works for me. I hope you find something that works for you.
