If you run, you are a runner. It doesn't matter how fast or how far. It doesn't matter if today is your first day or if you've been running for twenty years. There is no test to pass, no license to earn, no membership card to get. You just run.
Your small goals are clear and you understand the actions and know the path you need to take to reach these goals. In your mind, they're achievable and you know it's just a matter of time.
