I have an acquaintance who made good money on Wall Street for about ten years and then invested it all in a brewpub out in the country (near a ski area.) I don't think he's making much money and I hear he works all the time. But I think after Wall Street he realized he wasn't motivated by the money, and he was used to working all the time.

Now he gets to work with his hands, make something real people enjoy, and be accountable only to himself. I think he's pretty happy.
