I'm starting to realize that proper concentration is about blocking out whatever is going on in your head and then being attentive to what's needed whether it's reading for information or trying to complete some work. This is very important for my ongoing personal mantra so I believe this fits in now as a form of self-discipline.
My mantra is still in order: positivity, self-confidence, and hard work. I'm going to add to it proper focus on the most important things and self-discipline.
