I did a business in a box called College Pro Painters. They taught you how to paint houses, how to hire and fire, how to sell, how to deal with customers. You got a one-year franchise. It was the hardest year of my life in terms of hard work. I won manager of the year. It was very successful.

The toughest trail I ever ran was the Escarpment in the Catskills of New York State. This was an 18-mile race through Rip Van Winkle country, routed through boulder fields, across angular juttings of granite and along a path with an unrelenting barrage of roots, rocks and mud, all of it hidden under slick leaves and dangling nettles.

There's great stuff out there, but I prefer doing a TV show, going to work every day with the same people, and a lot of stuff is not being shot in Los Angeles and I don't really want to do that because my loved ones are here.
