Why NOT me?

So here goes. The other day I decided to get off the couch and start training for a half marathon. No, I'm not kidding. I need to lose at least 30 pounds. I have never run before and I really don't think I will love it any time soon. I have seen people on TV or in magazines that have lost weight and started running. I never thought it could or would be me. Then I started asking myself WHY NOT ME? Why can't I do this? Why shouldn't I try? Why have I given up before I started trying? I have done difficult things before. I have lost weight before. Am I really any less successful than anyone else? No. In fact I am more successful at some things than other people. I am motivated when I want to be. I can be driven to get things done. Why not this? Because I never have before. I am not athletic, or fast, or skinny or strong. Because I have never let myself be! Well, here's to a new beginning. Here is where it starts. Why not me?
