Few things under heaven bring more benefit than the lessons learned from silence and the actions taken without striving.
A good counter needs no calculator.
The Wise Man is square but not sharp, honest but not not malign, straight but not severe, bright but not dazzling.
Use justice to rule a country. Use surprise to wage war. Use non-action to govern the world.
For knowledge, add something every day. For wisdom....subtract.
The more clever and cunning people are, the stranger the events will be.
