How to stop feeling bitter toward friends who are more successful then me?

I don't want to be that person, but growing up, I was always the smart one in the group. The most hard working, and the most physically fit. I've always prided myself on that. I'm also reasonably educated. So when I see my old friends who were lazy screw ups, who took drugs, who dropped out of school, living better then me, well, I get a bit annoyed by that. One of these guys has a rich father, who has a business designing and building homes. He works around the clock. He gave his youngest son ( my friend ) 100% of the money to form a commercial electric company which 90% of his contracts are funneled into his business from daddy's business and his employees do all the work. So when he shows up with his 2nd million dollar speed boat and starts bragging to me about it, I smile and congratulate him and admire his boat. But on the inside I'm wishing to God that he sinks it on his maiden voyage. Does that make me a bad person? I don't want to be that guy. But apparently I am that guy. I hate that I work so hard for so little, while they work so little and have so much. I can't help but to feel some kind of way about that. Is that wrong?
