To be honest, I've been lucky enough to know a lot of successful people. Entrepreneurs, investors, and what have you. People have have been infinitely more successful than me at being intellectuals, businessmen, building wealth, etc.
I'm also a very competitive person, so other peoples fortune felt like my own failure - it's not rational, but that's how it sometimes felt.
But I found peace by just being happy for others. Jealousy and bitterness didn't make me any better, or motivate me more - it's self-destructive. You probably don't watch sports, movies, or similar and think "Wow, that person is so successful - why not me?" and feel bitter about it, so why should it be any different with your peers?
Focus your energy on being productive. Hell, seek out to the successful people you know, and ask for advice. Do they have any tips? mentoring can be a powerful tool.
