It would have to be my ADHD. The reason why is because it makes it hard to focus and I always have to move constantly, my mind also race and its really hard to stay on topic and its almost impossible to just think about one think at a time. Mostly because my mind would be thinking about lets say a cup and then I'll start thinking about why did the Chinese use bamboo instead of all the other trees in China. I think life would be allot easier with out it. In fact I probable wouldn't be here if I didn't have ADH.
