Kelley Millet

Kelley Millet is not a man to be trifled with. At college, he captained the football and wrestling teams, and he admits that as an investment banker he can be a hard taskmaster. "If you want to do this business," he says, "you've got to be fully committed.

I've always been of the view that everybody can give an A plus for effort, and as long as everybody does, then good things are bound to happen."

In Millet's case that means getting to work each day at 6:30am and, "assuming nothing's gone crazy", staying until around 8pm. "I do have a huge energy level," he says. "I'm most happy when I'm doing 15 things at a time.

That's a good definition of the kind of qualities you need in investment banking."
