"If you know the enemy and know yourself, you…

"If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle."

In the book

"If you know the enemy and know yourself, you need not fear the result of a hundred battles." — Sun Tzu (Sample epigraph — or use one of your own; you said it plainly in, that the biggest obstacle in life is yourself, and in, that we must first discover our own nature, and contend with it, before we can ever make peace with ourselves.) For seven chapters we have talked about what you need to fly — the shape of the flight, a plan, fuel, time, and the instruments you read it all by. […] Now the pilot — and knowing him is the labor of a lifetime. Sun Tzu's ancient counsel still holds: know yourself, and you need not fear a hundred battles; the wise man questions himself, while the fool questions everyone else. The first rule is simply to learn how to know yourself — to identify your own mind, your strengths and weaknesses, your real motives — because only once you see how you actually regard yourself can you begin to find your true self. — Who Is Flying (Self, Nature & Nurture)
