What people will thank you for…

Once when I was flying to Dallas with Zig Ziglar, he asked if I ever received letters from people thanking me. When I acknowledged that I did, he asked, “When you get those letters, what do people thank you for?” I had never really thought about that before, but the answer was clear. People almost always said thanks for a book I had written or some other resource I had provided. 
“It’s the same for me,” Zig said. “Isn’t that interesting? You and I are known for being speakers, but that’s not what prompts people to write.”
