Sun Tzu, The Art of War
A quick temper makes a fool. Chee

Impulsive men can be provoked to rage and brought to defeat.
One easily angered is obstinate and hasty - he does not consider difficulties.

One anxious to defend his reputation pays no regard to anything else."

W.K. Luck
Be alert, be wise, be ready, be brave. These are the rules of self-defense..."
