Whatever your determination or will power, it is foolish to try to change the nature of things. Things work the way they do because that is the way of things

Do not think dishonestly... Distinguish between gain and loss in worldly matters. Develop intuitive judgement and understanding for everything. Perceive those things which cannot be seen. Pay attention even to trifles. Do nothing which is of no use.

Accept everything just the way it is.

If you wish to control others you must first control yourself

The warrior is different in that studying the Way of strategy is based on overcoming men

To win any battle, you must fight as if you are already dead
