“Do it yourself” has been the theme of Bernie Marcus’s life. By the time he was 15, he had held more than a dozen jobs, still found time to join a gang, and worked as a comedian and hypnotist in the Catskills. Marcus overcame a hardscrabble upbringing to author one of the most entrepreneurial stories in recent American history: Home Depot. His journey was a wild one: 49 years old, and newly unemployed, Marcus teamed up with two friends in 1979 to try to build a better hardware store. That first day was so disastrous that the next morning, Marcus’s wife wouldn’t let him shave, because she didn’t want a razor in his hands. But they were passionate about their idea, and not afraid of failure. A decade later, they’d surpassed Lowe’s as the biggest home-improvement brand—and at the heart of it all was the concept of “do it yourself.” Organized around the three central tenets that have guided Marcus’s life—Dream, Build, and Give—Do It Yourself is an inspiring ode to entrepreneurship, grit, and the vision to think big.
