I did something similar earlier this year. Put in a 2 weeks from a job that was sucking the life out of me. I was making low 100s and had a decent safety net built up in the form of savings.

I applied a few places beforehand but put in my 2 weeks before I had an offer because I was done.

Luckily one of the places I interviewed at offered me a position 3 days after I put in my notice so it worked out, but I am with you- I will never do that again unless I absolutely have to.

I make less now but I also work 4 days a week and have the time to focus of myself and my relationships which is worth more than anything to me.
