What defines you?

I've been dropping Entrecards and reading some blogs. One thing that struck me on quite a few blogs is how people let one thing define them. That started me thinking. What defines me? Do I let one or two things define me? Are these good things? The answers to these questions are complex and not always easy. What defines me? Many, many things. What I do, what I enjoy, the company I keep, the hobbies I have, the things I do, the things I say, etc..... Those are just the things that pop into my head in the last 10 seconds. Imagine if I really put some thought into it?
Do I let one or two things define me? Ah....this was interesting. Giving it some decent thought I realized that sometimes I let this happen. I've been doing this more lately. I let one or two aspects of me take over and I become obsessive about certain things. Interesting....It opened my eyes.

Along those lines, one of the things that used to define me was my level of activity. I've let it slip in the last year or so but I'm working on getting it back. Towards that end I went swimming again. After going to school and running all my errands I hit Kailua Beach again and swam for about 20 minutes. It was great. It was still cold, but it was great. That on top of dragging my butt out of bed this morning to workout and I feel like a rockstar. It's been a while since I felt that way and that is something I want to define me.
