A change of pace

I'm friends on Facebook with a girl who lives in New York City and is a model. Sometimes I check out her page and her friends just to see what it's like for them to live there. It's so completely opposite of where I am now, and sometimes I just want to be a cliche and be some blonde outgoing twenty-something who moves to NYC and just has a blast all the time. I mean, I know they don't party all the time, but it is just a completely different world. It looks fascinating. I am just envious of those fashionable and successful and happy girls who aren't even ten years older than me. I'm excited to get older (to an extent), but I'm also worried that when I do, I won't end up being the way I wanted to.
