I think you took a unique perspective on the prompt; maybe even risky--which may be good depending on the reader. The part that troubled me the most is:
I tried to write about martial arts, about my job, about my school. Yet I felt false, phony even. None of those things encompass who I am who whom I completely share a mindset with.
This, in my opinion should be rephrased to something that says that these things are a part of you, but not the whole you. Otherwise it will seem like you've been wasting your time doing these activities and havn't taken much from them.
Another part that bothered me was:
As I mature, I hope that my generation will grow with me, and-ironically-learn how little we know
It sounds a little pompous and arrogant. You can change that by saying you will grow with your generation (rather then the other way around. Something should be done about the "learn how little we know part" as well.
Hope this could be of help.
