Immature strategy is the cause of grief.
Do not waste time idling or thinking after you have set your goals
Do nothing which is of no use.
When you have attained the way of strategy there will be nothing that you cannot understand. You will see the way in everything.
The important thing in strategy is to suppress the enemy's useful actions but allow his useless actions
With your spirit open and unconstricted, look at things from a high point of view.
