Firstly, to understand Martial arts, there's no one flawless arts in the world. Every martial art has its flaw. But every arts have its useful attack or defense. Choose wisely.

Secondly...Going into martial art world is not easy. Commitment must be there. Everything start from basics until all your kihon (basic) are firm. 'Cause usually people want to take a step forward, and doesnt really like the basic because they think it's boring and useless - but NO!

It takes years...to be a real martial artist. Train hard, and be commitment on one art at the time. Don't take more than one in a year, do ask advice from your sensei (after joining one art) if you plan to take a second one. Good Luck.
