I'm content with my lot (as far as humans go I'm doing OK), but it doesn't mean I'm not inspired to do more.
You're half right. Being inspired and challenged by the works of others is a great thing. But you should avoid comparing yourself to others since you'll frame it in such a way that you are either completely superior or completely inferior to the other person.
Plus, you don't have to frame yourself as "completely" anything, when comparing to others. You can focus on being a better mathematician, or a better business person, or simply a better human being, without automatically implying the other is "completely inferior"
