Hey, if you are more intelligent than 99% of everyone else, you're going to feel bad until you arrive in the 99th percentile for wealth and material success.
I totally disagree with this. I know a lot of 99th% people in terms of IQ, very few of whom are in the 99th percentile for wealth. (I think I know exactly one person who fits both descriptions--and she is not that happy, IMO.) While some of them may not be totally satisfied with their lives, certainly many don't feel bad about themselves at all.
