Remember, you have no companions but your shadow

All who surrender will be spared; whoever does not surrender but opposes with struggle and dissension, shall be annihilated.

I hate luxury. I exercise moderation…It will be easy to forget your vision and purpose one you have fine clothes, fast horses and beautiful women. [In which case], you will be no better than a slave, and you will surely lose everything.

If unable to abstain from drinking, a man may get drunk three times a month; if he does it more than three times he is culpable; if he gets drunk twice a month it is better; if once a month, this is still more laudable; and if one does not drink at all what can be better? But where can I find such a man? If such a man were found he would be worthy of the highest esteem.

Heaven is weary of the luxury of China. I shall remain in the wilderness of the north. I shall return to simplicity and moderations once again. As for the clothes I wear and the food I eat, I shall have the same as cowherds and grooms and I shall treat my soldiers as brothers. In a hundred battles I have been at the forefront and within seven years I have performed a great work, for in six directions of space all things are subject to one ruler.

One arrow alone can be easily broken but many arrows are indestructible.
