Awesome thread, I like the idea of 10,000 reps. I think it is the pursuit of 10,000 reps where you learn to become a real ninja with a certain technique.
Some people will learn things more quickly than others, if you stay focused and disciplined in your studies and drill a lot, with the idea that you want to hit 10,000, then you are getting the point. The way I interpret it is that the pursuit of excellence is a life long event with non stop practice and continued growth.
If you just develop these kind of habits in Jiu Jitsu they will spill over into your personal life. I will never stop drilling, the by product is only limitless future with limitless potential.
