Types Of Knowledge

知彼知己，百戰不殆；不知彼而知己，一勝一負；不知彼，不知己，每戰必殆

“If you know your opponent & know yourself:
you will WIN 100 battles easily;

If you don’t know your opponent, but do know yourself:
you will sometimes LOSE and sometimes WIN;

If you don’t know your opponent & don’t know yourself:
you will LOSE every single battle.”

– Sun Tzu – 496 BC, Chinese general, military strategist, and philosopher
