I know a dentist. Bought out the old guy and took over the practice 5 or 6 years out of college. Old guy gets to come in 3 days a week, if that much. Practice is in South Florida, so he's busy in winter, slack in summer. Lives on the water, addicted to boats. Makes plenty but not $300k.

And he's absolutely bored to tears. Hygienists do all the work. That "file" he looks at when he comes in? It's all crib notes on you, so he can pretend he remembers you. "Oh hey, how's Delta? Kids doing okay?" He pokes around for 5 minutes, claps you on the back, heads back to the office to look at Boat Trader. Maybe gets to pull a tooth or do a root canal once a week if he's lucky.

I can see his mid-life crisis coming a mile away. The only question is: what form will it take?
