“You can buy a man's time, you can buy a man's physical presence at a certain place, you can even buy a measured number of skilled muscular motions per hour or day. But you cannot buy enthusiasm, you cannot buy initiative, you cannot buy loyalty; you cannot buy the devotion of hearts, minds, and souls. You have to earn these things.”
