Even with the staggering pile of numbers that Buffett sifts through, and even though he works like the dickens, Buffett is no type-A boss. “Yes, I need roller skates to keep up with him,” says Debbie Bosanek, his secretary of nine years, “but I’ve never seen him get mad. I don’t think he’d like to be lied to, though. If you make a mistake and tell him about it, that’s okay, but you wouldn’t want to cover it up.” Adds Tom Murphy, the founder of CapCities: “He wakes up every morning and goes to work to have fun. It’s not work. He’s only with people he likes, so he isn’t stressed out.”
