I was diagnosed with ADHD my freshmen year of high school. I was never failed a class because of it - I was actually, a really good student. I was so impulsive all the time and would never stop moving. I think this is why I was a good athlete. My impulsiveness got me into trouble a couple of times, but once I started taking medication for my ADHD, I was back on track. I stopped taking the medicine before college, because for me, my ADHD was a maturity factor. I loved running because there was always something to see, to hear, to do. Your body is always moving. I think this is why I still loving running and training for marathons. Your body never moves the same way, and you always have something to look at to keep your brain active. My thoughts are everywhere but it makes running more fun! My ADHD was not a serious case, but being an athlete has helped me significantly and running, in general.
