Before you start a fight, make sure you will win it.
Give yourself as big an edge as possible. Make it impossible for the other guy to win.
Fight unfair.
Don’t take a sword to the knife-fight. Take a gun.
If its a fist fight, take a knife. If its a gun-fight, take a tank.
Win the fight before it begins.
If you can’t be sure of victory, don’t fight.
