I took what I call a 12 year sabbatical from tech. I became an officer, went to pilot training, learned lots of new and useful skills, met lots of very good and interesting people, some of whom are my best friends.
Taking off from a short airfield in a blizzard, at night, wearing NVGs is an experience I don't care to re-live, but I'm glad I have something to talk about at parties.
A quote that affected me greatly during the time I was thinking about leaving: "if somebody wrote a book about your life, would anybody want to read it?"
After getting married (to somebody I met during one of my training courses), settling down, and having kids, a quieter, 40-hour-a-week lifestyle started to sound pretty good again. I had always been a hacker at heart, and realized that I was getting to the age where it was probably now-or-never if I wanted to re-enter the industry. So I went back into tech! It's better the 2nd time around.
Zero regrets.
