It's hard to be sure, Fin. When I quit, it was a decision I did not make lightly. Then, when I felt better and began a new career, I could not get insured. So, I did some contract consulting for a few years. When I saw how fast I've been going downhill a few years ago, I reordered my priorities to do everything I've ever even thought of doing. I'm almost finished and have never once regretted that decision.
When I really think about it, the things I miss most about working are the people whose intelligence I deeply admired, walking around downtown wearing tennis shoes with a skirt suit, the lunches with colleagues, and communicating with officers of major corporations.
Mostly, I miss the kicks I used to get from doing those things. Now I get my kicks in other ways.
