Really good answers so far, but "looking like Bruce lee" takes the cake haha i thought this kind of thread needed some humor in case everyone had the same answers like, was bullied, saw jackie chan, weight loss, etc. (but really, who wouldn't wanna have that kinda physique?) But if you want more of a serious serious answer. I don't know how to describe it. Can I say that maybe it's also the feeling you get when you step on the floor? do you all feel this feeling or is it just me? freshly cleaned dobok/gi. you bow to your grandmaster/sensei. The smell of sweat and training equipment. you do your deep breathing exercises, and it's like you're soaking up all the history from previous martial artists that have walked the same path as you, for hundreds of years. wearing the same uniform, doing the same techniques, the same traditions. passed down, to you, and you will eventually pass it down to the next journeyman. you just zone out, get tunnel vision, and focus on the snap of your uniform at the end of every movement in your hyung/kata. That one hour, where i'm in another world, and everything is alright. that one hour of serenity and bliss, that "feeling" is why I train.
