When I was 30, I set a goal of being able to retire at age 50. I’m still on track for that goal, but with my 44th birthday coming up next month, I now wonder what the hell was I thinking. I don’t want to retire. I get bored on a three-day weekend. I need to have mental activity, variety, and the sense of purpose and fulfillment that comes with work. So, no, I won’t be retiring at 50 even if I can.
