I love the competitive aspect of it [business]. It's like playing chess. Why do people play chess? Knowing the realm of moves? Even when you get to be a chess master, there are other chess masters you want to beat or outperform. And to me business is just a sport that I love to compete in; a continuous intellectual challenge that really motivates me.
