It is all in my head. I keep telling myself this because I know it is true. This is true for eating right, for going to the gym, for running a race. I somehow convice myself that I cannot do it. I don't have the will, strength, etc to do it. I KNOW it is all in my head. I have eaten better. I have gone to the gym on a regular basis. I have not only started plenty of races but have finished every one I have started. So why do I do this to myself? Why does my head keep telling me I cannot do this. That I will fail? I know that if I stumble & fall that it isn't a failure. I know that if I don't reach my goals now that doesn't mean I won't. That I cannot. I heard a quote once "a loss is not a failure until you make excuses." I know there is no excuse for why I am overweight. There is no one to blame. I am responsible for my own actions. I KNOW all of this yet my mind keeps trying to mess with me. 

So I will not quit. I will not stop. I am stronger than my greatest weakness, which is myself. After all it is all in my head.
