“I have spent considerable time, money, and effort in the past on various martial arts like Brazilian Jiu-Jitsu, Krav Maga, etc. and after the success of this weekend, I wish all those other “Arts” would give me a refund. Never feel like you waste any time. Everything is streamlined with a purpose and offers a physical learning that “sinks in” even before you have conscious recall of all the targets you were just introduced to.”
