It Depends On You

Last Monday I had a White Belt ask me after his first class, "so do you think we have a shot at learning it?"
My response to him was this, "That depends on you. We're only with you for three hours a week. The rest of your time depends on what you're willing to put into it." Practicing outside of the class makes the biggest difference.
You wouldn't only eat three times a week, you'd be miserable, weak and pathetic. The same goes with Kenpo. You won't get very far by just practicing three times a week, you have to feed that fire. Continue to create that muscle memory, build your intensity and most importantly understand the principles and the concepts that lie within what you have learned.
Asking questions is a huge help too, I understand that after a hard class when you're drenched in sweat and all you want to do is collapse that the last thing you want to do is ask questions. That's what a notebook is good for, if you can't ask it right then, write it down and come back with the question later. Again it depends on you, I believe that every student has the potential and the ability to make it to Black Belt. However you will only get out of this Art what you put into it.
