Do unto others what you want done unto you.
Between friends, frequent reproofs make the friendship distant.
He who merely knows right principles is not equal to him who loves them.
Riches and honor are what everyone desires, but if they can be gained only by doing evil, they must not be held. Don't worry about not being in office, worry about qualifying yourself for office. Don't worry that no one knows you, but seek to be worthy of being known.
Transport a handful of earth everyday and you will make a mountain.
Heaven gives long life to the just and the intelligent.
