Am I the only one who worries about these things?

Musing. Thinking. About personalities and characters.
College is coming up so soon, and to be completely honest, I feel like I have to pick a persona. You know? Who I actually want people to see me as. Well.
The logical (and probably right) part of me says: "That's what college is for! Learning who you are! You don't have to have it figured out before you show up. You're thinking too much! Again!"
The.. uh.. illogical? right brained? Well, whatever you want to call it side of me is thinking "Do I want to be the ever elusive mystery? Do I want to be open, honest, and transparent? Do I want to be affable and friendly? Do I want to be part of every club, organization, and committee?"

Well. This is hard.
But is it important? Or completely unimportant?
I've always sort of felt like if you change the way people see you, you've lost some kind of credibility with people. They may or may not feel like you're being false, when you present an idea that seems out of character, start being more honest, or start dressing differently.
I guess that is what is prompting me to try and decide now. So that I don't "lose" the "credibility" (in my mind). So that I can be set, and I don't have to change later. But shouldn't I want to change? Shouldn't I be striving to be better, and to know God and myself better?
Yep.

We can be whoever we want. These people don't know us (mostly). We can start all over.
Is that the beauty of college? Or the down fall?
Do we try to be something we're not? or something we are, we were just too afraid to show before? Am I the only one who worries about these things?
