Arthur M. Blank believes that for good companies, purpose and profit can-and should-go hand in hand. Arthur found incredible success by doing just that with his company Home Depot. The rest is history. Blank stepped down as co-chairman of Home Depot in 2001 and the next year he bought the NFL's Atlanta Falcons for $545 million. Today, the team is worth an estimated $2.8 billion and recently played in the Super Bowl. Arthur shares his wisdom on building "good companies."
