It is easy to love a friend, but sometimes it is the hardest lesson to learn to love your enemy.

The worst calamities that befall an army arise from hesitation.

Do not swallow bait offered by the enemy. Do not interfere with an army that is returning home.

One may know how to conquer without being able to do it.

The whole secret lies in confusing the enemy so that he cannot fathom our real intent.

Begin by seizing something which your opponent holds dear; then he will be amenable to your will.

Plan for what is difficult while it is easy, do what is great while it is small.

Ponder and deliberate before you make a move.

Great results can be achieved with small forces.

Be where your enemy is not.

If the mind is willing, the flesh could go on and on without many things.

Wheels of justice grind slow but grind fine.

Never venture, never win.
