There is nothing wrong in finding inspiration in someone else who is better than you, to help build a better version of yourself. There is a subtle nuance between this and feeling jealous or envious.

The main reason why I used the verb 'compare', is because we are taught to think in terms of adversity/competition when it comes to learning in almost any field. I strongly believe that learning should only be about learning. And it turns out that if you learn the right things and if you work hard, for the sake of being good at something, then you will likely be highly ranked. But that should not be the goal.
