Wisdom is not a product of schooling but of the lifelong attempt to acquire it.

First they ignore you, then they laugh at you, then they fight you, then you win.

To know your Enemy, you must become your Enemy.

Don't get set into one form, adapt it and build your own, and let it grow, be like water. Empty your mind, be formless, shapeless — like water.

Let your opponent graze your skin and you smash into his flesh; let him smash into your flesh and you fracture his bones; let him fracture your bones and you take his life. Do not be concerned with escaping safely — lay your life before him.
