Tim Sanders was raised by his grandmother, from the age of five until he graduated from high school. Grandma Billye, who is now 96 years old, loaned him $100 to start his first business, a fireworks stand he established in the 8th grade. When he hired friends and gave too much to them, she helped him understand profit margins. “You’ve got to get better at hiring people,” she told him.

Billye showed Sanders the lesson of the pecan — “eat the nut, dump the shells” — after he was teased at church camp. They called him squeaker because of his high voice. Billye showed him a pecan and asked him, “Can you eat this thing?” He said, “of course not,” and was then told to crack it open. “Every piece of criticism is a pecan,” Billye said. “Your job is to crack it open and find the nut and throw away the shell. What can you see that’s good? Every piece of criticism is a gift. Every failure is a gift — if you throw away the shell.”
