Now that you're sort of free from the constraints of a normal 9 to 5, perhaps it's a good time to consider doing jobs that you might have not considered before.

Now that you're sort of free from the constraints of a normal 9 to 5, perhaps it's a good time to consider doing jobs that you might have not considered before. A lot of very skilled friends who've retired from industry ended up doing non-profit work and found it very satisfying. From my own experience, as an engineer still working, my time spent as a volunteer are among the things that gives me the most satisfaction. I'm about as satisfied at having run marathons, been part of an IPO, done some good engineering work, and literally put 200+ roofs over people's heads as a roofer for Habitat for Humanity. Mentoring high school students from East Palo Alto and seeing them graduate and becoming the first college students in their family are among the works I've found most worthwhile. Non-profits often need the type of specialized skills people like you can bring but can't afford.
