Pen Spinning

Recently I saw a video on you tube about pen spinning and I'm now addicted to it. I have been trying to do the tricks in all my classes every chance i get, but I'm failing miserly. Every class i drop my pen easily over 100 times. The main pen spinners are in Japan where its a sport and they are insanely good at it. I need to stop this pen spinning business, but its very addicting. I find myself not focusing as much as i should in class and starting to rage after dropping it several times.
