Why do I want to blog?

I guess the biggest question of the day is "why (do I want to) blog the things I go through with my struggle with my weight?" I'm not really sure. I guess I am really looking for a way to record my feelings and what I learn along the way. Right now I'm struggling with making time for exercise. I have this wonderful elliptical trainer. It is new and I'm very proud of it. However, it kicks my butt evertime I get on it! How can a child of 6 run his legs off and I feel like a Mack truck has hit me after the first 8 minutes? ~Guess that's just one of the uphill battles I have ahead of me!
