Tao Te Ching Chapter 24
He who stands on tiptoe does not stand (firm);
He who strains his strides does not walk (well);
He who reveals himself is not luminous;
He who justifies himself is not far-famed;
He who boasts of himself is not given credit;
He who prides himself is not chief among men.
These in the eyes of Tao
Are called 'the dregs and tumors of Virtue,'
Which are things of disgust.
Therefore the man of Tao spurns them.
