Envy is the one deadly sin that nobody admits to. To reveal our sources of envy makes us look petty and feel ashamed. I am riddled with envy, sometimes for ridiculous things. For example, I envy the people leaving the gym as I get there. It was in the gym that I learned an important lesson about envy. Many years ago I went up to a guy resting after a set of pullups. I said, "You are what the rest of us long to look like." His response surprised me. "No, that guy over there has the best physique." It struck me that no matter how good we look, how much we acquire, or how successful we are, it's never enough. Envy has a way of seeping in and making us unsatisfied with our condition. We are always at the mercy of envy.
