Lol I used to play football too! All the way up to freshman year in college.
I still remember something my high school coach told me the summer before sophomore year. He asked me if I was going to be great, and Idk what I answered. And he said, "JCTWP46, you have to believe that you are going to be great. Because if you don't believe you're going to be great, then who is?". I think he was talking about more than football and its something that has stuck with me since.
He also made me look up the definition of the word mentality and put it on my mirror at home. Thats something else that has stuck with me for a long time. A lot of people didn't like him as a coach and actually filed a lawsuit and got him fired for actions that I never saw take place. But, I really liked him and thought he was great. He's somewhere else in the state now coaching at a big, successful high school.
