I can give you 30 examples right now. Bob Combs, the pig farmer in Las Vegas who collects the uneaten scraps of food from the casinos and feeds them to his swine. Why? Because there's so much protein in the stuff we don't eat, his pigs grow at twice the normal speed, and he's one rich pig farmer. He's good for the environment, he spends his days doing this incredible service, and he smells like hell, but God bless him. He's making a great living. You ask him, "Did you follow your passion here?" and he'd laugh at you.
