Pell Talk: - Your Hit List.
Every competitive, or would-be competitive, fighter should create a "Hit List." This is where you list all of your competition, their strengths and weaknesses, and your record fighting those opponents, with notes. This gives you a huge advantage over time in your quest to learn and surpass all of the competition in your area/sport. It's too much to try to keep in your head and recall for study. Write it down and check them off.
