I have been developing for 30 years professionally and 10 years before that as a hobbyist or in school

Development is solely to exchange labor for money.

I haven’t written a single line of code “for fun” since 1992. I did it for my degree between 1992-1996 while having fun in college and after that depending on my stage in life, dating, hanging out with friends, teaching fitness classes and doing monthly charity races with friends, spending time with my wife and (step)kids, and now enjoying traveling with my wife and friends, and still exercising
