Proud because I kept a promise to myself

Today, and admittedly as part of a bet, I decided to run for a whole hour. Now, I'm not exactly the running sort anymore; I don't particularly enjoy running, and I haven't trained in a very long time. Today, however, I proved to myself that I still had it in me to run like I used to, and kept my promise to myself that I would. I surprised myself-- I guess my cardio is still in pretty great shape. I've always believed that if I wanted to do something badly enough, I could do it, and today I confirmed that belief. All I had to do was believe in myself, and remind myself how proud I was of how I was doing, and sort of be my own cheerleader throughout the whole thing. Back in the day, I used to run for multiple hours at a time, and several years have passed since then. But today, I found that it is truly strength of will, not body, that matters most, and that is why I'm proud of myself. (:
