>> What's the best way to exit tech?

Harakiri!! :))

Otherwise getting serious the best approach would be to take a few alternative jobs part time, just to get a taste of the other side. Stacking shelves at Target. Truck driver, butt in the seat for 12-16 hours (illegal technically but if you don't do it you're out of the job), piss in a bottle, away from home for weeks at end. Sales, not hearing a word of kindness your entire existence only how you're missing targets and hang on a thread. Become a hermit and go live in the woods for a while.

You might be dreaming of grass being greener on the other side but my point is that it's mostly brown. Shitty brown, that is.
