The start of Home Depot sounds like the beginning of a bad joke: In 1978, Bernie Marcus's livelihood depended on just such a scenario. Having been fired at the age of forty-nine, he teamed up with Arthur Blank and Ken Langone on a bold new endeavor. Their first day in business 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 the last laugh would be theirs, as the business partners grew Home Depot into the world's largest home improvement retailer, empowering millions of Americans to "do it yourself." "Doing it yourself" has been the theme of Bernie Marcus's entire life. By the time he was fifteen, he had held more than a dozen jobs, joined a gang, and worked as a hypnotist in the Catskills. The son of a cabinetmaker and garment worker who survived the Triangle Shirtwaist Factory fire, Bernie overcame a hardscrabble upbringing to author one of the best entrepreneurial stories in American history. Today, Home Depot employs 500,000 associates at 2,300 stores and is one of the most recognized and admired companies in the world. The same energy that made Home Depot successful has helped Bernie give away more than $2 billion and pioneer a new model for philanthropy, transforming millions of lives. There is no single, winning formula for trying to make the world a better place, but Bernie shares what he's learned—that the skills needed to build a Fortune 500 company are the same ones that can help cure cancer, treat veterans with PTSD, and transform autism treatment. And it doesn't take a fortune to make a big difference in your community. will inspire you to dream, build, and give—and, maybe, change the world.
