When I turned 18, my father took me aside to talk about my future. "I don't care what you do for a living ", he said, "as long as you don't go into education." I obeyed to a point. I never did go into academia; I didn't become a schoolteacher or a professor. But I currently run a business that teaches craftsmen and professionals how to master the fundamentals of business on their own terms, without spending years in school and without racking up six-figure debts.
