Either push your limits or die.
In order to control myself I must first accept myself by going with and not against my nature.
The possession of anything begins in the mind.
There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
Low aim, not failure, is the crime.
When you fight, if it is a real fight, use every tool that you have, use your whole body. Use your fists, your legs, your fingers, your head if you have to, and hit them in every vulnerable spot, the balls, the eyes etc. to win.
