It’s like a marriage. You need to like each other. And if you treat people right, you will love them. I told my customers that I liked them, that I loved them, all the time. I would send a card every month with a different picture, a different greeting, and the card would say, “I like you.” I would close a sale, and I would say to my customer, “I love you.” I even gave them buttons that said “I like you.” People may have had to wait for an appointment, but when I was with them, I was with them body and soul.
