when I left Google to work in clean energy, I took a 50% pay cut. But, that's still more than enough money to live very happily on. IMO it's true what they say about there being no marginal improvement to happiness after ~80k.
Glad you're happy, I also want to get out of my current industry eventually. How much was 50% actually? For all I know, you could have went from 400k -> 200k. Do you live in a HCOL area?
