Pete Favat talks about building useful things from scrap and renovating his home on "This Old House." The C-suite leaves less time to get his hands dirty on the job, he says. "You're using your brain, which is good, but there's no physical gratification at all. We weren't put on this earth to just bang keys on a keyboard." So he creates on his own time, putting together whatever strikes his fancy: a dog sled, a chandelier, a garden.
