I...can't say I've ever felt that. XD; I admire people but that doesn't necessarily make me jealous of them, I know I have my fair share of skills and that alone helps me get through pretty much anything.
This.
I don't think I have ever really felt compelled with jealousy over one of my friends and something they may have the ability to do that I cannot. Like said, we all have our own share of abilities or skills that others may not have, which makes us all unique. Sure there are things that others can do that I wish I was capable of, but I'm satisfied of what I have potential to do as well.
