This means that it is very important to know your strengths and your weaknesses and know the same for your enemy as well. When you know yourself and know your enemy, you are far more likely to win the battle.

When you only know yourself, but don’t know the enemy, then you may win a battle, but you may have major damages as well.

When you don’t know what your weaknesses and strengths are, then you will most likely fail to resist to your enemy and have major damages as well.
