I'm the knowledge manager for a state (US) utility regulator. For 10 years before that I was a policy specialist for the same. I didn't get a real job until I was 36. Before that: student, logger, laborer at a sand and gravel yard, street person, dishwasher, cook (Mexican restaurant), environmental activist . . . First professional (paid) band at age 46. It's never too late for new challenges. Okay, never say "never". But it's not too late yet.
