I have a close friend who's sort of similar to me, and I'm afraid he's becoming more sociable and outgoing. Am I selfish for wanting him to stay introverted like me, because I sort of feel an obligation to be happy for him. It's also that even though he sorta looks up to me, he's getting better at the stuff I'm also talented at. I feel like he's going to be great and successful in life while I fall behind and do pretty much nothing. Anyone have words of advice, or are in similar situations?
