Everyone compares themselves to others. It's not healthy when it connects to the person feeling inferior, but on another hand, it can be healthy. Some people may be good to compare yourself to: some may find it better to find a role model, someone who works hard, someone who is capable of doing good despite having it rough perhaps. Of course I'm comparing this to attitude, not looks. You can look at our perfect society for that.

That's really how it is! If people would stop being jealous of one another for just a moment, life would be so much easier for everyone. Because there's really nothing to be jealous of! Everyone's unique, and who knows? When that girl sees you, she might think the same thing. Well done.
