You are Judo
You are a smart, measured person who doesn't let feelings or instant reactions get the better of you.
You have a gentle way about you, even when you are being attacked. You don't face anyone or anything head on.
In life, you like maximum effort for minimum results. Even when you do something amazing, it's through brains and not brawn.
People don't understand the reasons for why you do the things you do. You can seem brutal even when you are being extremely docile.
In a battle, you are equally offensive and defensive. You are on your toes, and deciding your next move on the fly.
You may seem like a reckless or wild fighter, but every move you make has a deeper, unseen purpose.
