It's an interesting to consider but I agree that everyone is different. It's common to envy some people, and for them to envy you back. Everyone's situation is different and there are things that others are better at. We are all just trying to live our lives.
Well I think there's a "healthy envy" if there's something like that. I think in this situation people just admire others in a healthy way and just want to improve their lives because of the how the lives of the other person has challenged them to.
