Here's how my dad got to early retirement. He was different than me.
Dad was a chemist, graduating from Roosevelt University in the 50s. Not long after getting his degree, he and a chemist friend decided they wanted to try setting up a small chemical company startup in Mississippi. Off they went, wives in tow.
Things didn't work out (and I don't think they had bargained for summers in the Gulf region), but they were there long enough to have their first baby - my oldest sibling. They came back to Chicago and Dad took a position as a staff chemist at a more traditional, established company. He stayed with them his entire career and worked his way up to becoming a director of a research lab.
He'd hired two young guys he thought the world of: bright, motivated, likely good future with the company. One day he got word from upper management that due to budgetary constraints he had to let one of them go. Nothing to do with performance. He had to choose which.
He agonized over this for a few weeks then hit upon a solution: he retired! Both guys kept their jobs, and he got to move on and do things he enjoyed: relaxation, a little short travel, cooking, beer, and lots of time hanging out with the dogs.
I have a friend who is Chinese and a lifelong practicing Buddhist. One of the most peaceful people I know. I told him this and he listened quietly. When I was done, he just sat back, smiled, and said, "That's good karma".
