What Your Enemy May Lose

Before you start a battle or war, evaluate what your enemy can lose not only what can you gain. If your enemy don't have anything to lose, then you are doing your biggest mistake by starting a battle with him.

If you know what your enemy may lose and you evaluated it as valuable, then you can use this loss opportunity to leave heavy pressure on your enemy to surrender for your demands.

On the other hand, try to hide what you may lose if your enemy started a battle against you.

Know Your Enemy

Says the great war leader Sun Tzu in his book the Art of War, if you are unaware of your enemy and unaware of yourself, then you are an idiot and for sure you are going to be defeated in every battle.
If you are aware of yourself but unaware of your enemy, you are going to win every battle but carry great losses.
If you are aware of yourself and aware of your enemy, then you are going to prevail in every battle.
