I don't know why I'm wired the way I am, but I'm just not susceptible to envy--at all. However, I hardly think that most people successful or otherwise are like me. In fact, I'd say a good bit of successful people are so because of their envy.

Envy is the worst of the 7 deadly sins. It's like Charlie Munger says, "It's the only deadly sin you're not going to have any fun with."
