Been retired 11 years now, (73), love it.
Loved my teaching, totally detested the pathetic waste of time admin work that solved nothing.
stupid paper work for its own sake that took up more time than actually teaching.
BUT, I've said it before, you will need other interests, preferably more than one else the dreaded sit in the chair staring out the window will get you.
Two of the guys who were younger than me but left at the same time are now dead, they had no hobbies or interests.
I dont see that happening to anyone on here, we all seem to have so many projects that theres no chance of getting bored.
I took early retirement for 2 reasons,
1, as listed above
2, so I was still young enough and healthy enough to travel which I did, Philippines (twice), Singapore, Malaysia, Japan (3 times), China, America, Canada, just getting ready to book Korea and Vietnam when covid hit.
Do what you want asap before any regrets get any chance of settling in.
