The most classic one is: Don’t do evil because it’s small, don’t do good because it’s small. Zhuge Liang's "Book of Commandments": Don't ignore small gains and neglect repairs, and don't ignore small losses and fail to prevent them. Don't neglect your loved ones with petty resentments, don't forget old kindness with new grudges. A mountain can be as high as it is without skimping on earth, and a sea can be as deep as it is without skimping on water. If you don’t accumulate steps, you can’t build a thousand miles; if you don’t accumulate small streams, you can’t build a river or sea. The accumulation of soil creates a mountain, and wind and rain stir up it; the accumulation of water forms a abyss, and dragons emerge; the accumulation of good deeds becomes virtue, and the gods are contented with themselves, and the holy heart is prepared. Therefore, if you do not accumulate steps, you cannot reach a thousand miles; if you do not accumulate small streams, you cannot reach a river or sea. A horse can't take ten steps with one leap; a horse can ride ten times without giving up its merits. If you persevere, the rotten wood will not be broken; if you persevere, the metal and stone can be carved. Earthworms don't have sharp claws and teeth, nor strong muscles and bones. They eat earth and drink from the underworld. They have the same intention. A crab with six knees and two pincers is not a snake and eel that has nothing to rely on in its cave, so it means it is impatient.
