"When I would sell encyclopedias, I would drive down the road looking for a house with a swing set in the back, and I'd say, "Oh, those folks got kids. They need some books." I'd knock on their door and sell them a set of encyclopedias, and those books were from $300 to $600. I'd look around the house, and if there wasn't that much furniture in the house, I felt a little bad about selling a $600 set of books to people who couldn't afford a couch. So I didn't last at that job very long."
