"Eventually, it clicked, and I learned one of the bedrock principles of salesmanship: Whether you’re peddling long distance over the phone, Bibles door to door, or your own political candidacy on live national TV, it doesn’t matter what you’re selling—it matters how you make people feel. If you make them feel good, they’ll say yes. If you don’t, you could be selling a pill that reverses male-pattern baldness and makes you lose weight without exercise, and they’ll still turn you down flat."
