Benjamin Franklin.1 What he actually said was that every person should be a “Jack of all trades, master of one.” He was making the exact opposite point. He was saying that every one of us should get incredibly good at one thing. Sure, be well-rounded, know a little about everything, dabble if you want, fine. As long as you’re a master/craftsman/specialist/expert/scholar/authority/black belt/maestro of one.
