I'm not a writer, but I use to be. I stopped writing because I was feeding into a deep seeded depression that wouldn't end while I was still writing. Am I a writer? Not anymore, no, do I identify with writers and respect their work? Yes, I do. On that note, I'm not an artist either, I can't draw/paint to save my life, but I do enjoy and respect the work of great artists.

But I think that 'wanting' to be something IS in fact an aspect of our identity. Let's say someone wants to learn to play the piano, they aren't a pianist, but they are learning. The very fact that they are attempting to learn is part of who they are.

You're identity, very simply stated, is that which you identify yourself with; i.e career, political affiliation, religious views, hobbies, ect. So if you workout on a regular basis you might consider yourself as someone who is fit, and others would see by you're actions that is a part of what they may identify you as.

Character on the other hand is perhaps the essence of who we are. Are you the type to help out those less fortunate than yourself, or are you a hard worker? Do you take pride in what you do? Can you genuinely feel happy for another persons success? These are things that define one's character.

Then personality would be how you react to your environment. If you're a passenger in someone's car do you get uneasy because you are not in control of the situation? Are you comfortable meeting new people and networking?

Just my opinion if you really want to break these down, I feel like labeling is a bit dangerous though, simply because it can lead to stereotypes and prejudice.
