Avoid violence of any type, move to the coast, buy a surfboard. This will teach you balance, make you fit, calm your mind, put a smile on your face.

There is no logical sense in learning a system of violence (defensive or otherwise) to improve your body and mind.

Goal Setting - I'm gonna paddle this board through this beach break like a dolphin

Persistence - Opps, it just dumped me on the beach - try again

Confidence - Cool, I made it to the line up

Nutrition - I eat a Paleolithic hunter/gatherer diet. No carbs, no dairy. Food my body was designed for.

Physical Fitness - Paddle, swim

Frustration Tolerance - Repetition, learning, fun

Focused Attention - All I can think about is this wave

Sportsmanship - It's a big ocean, go for it buddy

Who's the best surfer? the one having the most fun.

And BTW, yes I've done my share of martial arts training. If what you really want is to learn how to kick ass, go here: www.russianmartialart.com
