What is this innate need to have “passion” for a job?

I was a hobbyist programmer from 1986-1992 programming in Basic and assembly. But after that, it became a means to an end - to support my need for food, clothes and shelter while doing other things that I enjoyed. I went to college, enjoyed the college life and got my degree.

I spent 1998 - 2012, hanging out with friends, teaching fitness classes more as a social outlet than a second job, had a bad 4 year marriage in between.

I got remarried in 2012, stop teaching, started taking my career more seriously while raising a 9 and 14 year old (step sons) and when the youngest one graduated in 2020 and after COVID lifted, my wife and I hang out after work, we travel and she pursues her hobbies and I pursue mine.

There has never been one day that I thought “I can’t wait to get home after spending all day on computers to spend more time on my computer”
