A lot of people work really hard at jobs they don't particularly like, so that when they can get old they can retire and go fishing or play golf or travel, or lie around the pool.
I started doing all that 45 years ago because I played music at night and had all day free.
When the music gets to where I don't want to do it, I'll quit. Or when they tell me to quit, that would do it too.
I was fortunate enough to make enough to support myself and my family for a long time, but often things were quite bleak. Something always turned up and I took the occasional "day" job when absolutely necessary. My wife does have a very good job which takes care of our insurance, so that has been a big help. These days, she makes a lot more than I do as well, but then she is a young thing (59) and I've been on SS for fourteen years!
When I had a real job, I totally hated having to get up and be somewhere at 8 in the morning, even though I had a fine and interesting occupation. Along the way I owned a few businesses, including a golf club company, driving range and night club. None of them seemed like work at all!
If I had it all to do over, I'd probably make a few changes. Such as not wasting those first 10 years working!!
