God, so much - I consider myself a bit of a pro at this:
Gave up stressful high-powered job for much calmer, nicer one - return on energy beggars belief.
WFH so no more commuting
Gave up any 'frienemies' years ago.
Ditto all social media.
Currently happily single, so gave up all of ex-DPs nonsense that his new partner can now 'enjoy'.
Only do full cleaning about once a month - basic wiping etc. in the meantime. Almost no ironing.
Gave up wearing heels long ago.
Never attend things I don't want to anymore.
Sometimes I wonder what I DO give any fucks about anymore, but then I remember that it's my interesting work, lovely friends, reading, walking in nature and running. Happy days.
