There's only been a couple users that I've felt this way about, to be honest. I'm dating one of them, and the other user. . . Ugh. I envy them to death.
I never tried to copy another user, but I did try to emulate their style a little bit. . but sucked so horribly. e_e And really, I felt like such a hypocrite for trying to mirror their style a bit. Sure, Imitation is the highest form of flattery, but frankly I find it annoying yet I tried to imitate them a slight bit. Ugh. So, that's when I said, "Enough. I give up." And just went back to doing me.
But honestly, if I had the riches and the style like these users have. . . s**t, son, I'd be set. I'd be happy. But at the same time, would I really?
So, right now I'm just happy doing my own thing and evolving my style. It's ok to envy another user once in a while, and it's ok to privately emulate their style once in a while, I think. Just don't straight up mimic them! Some people go too far with that sometimes!
