He who stands on his tiptoes does not stand firm; he who stretches
his legs does not walk (easily). (So), he who displays himself does
not shine; he who asserts his own views is not distinguished; he who
vaunts himself does not find his merit acknowledged; he who is
self-conceited has no superiority allowed to him. Such conditions,
viewed from the standpoint of the Tao, are like remnants of food, or a
tumour on the body, which all dislike. Hence those who pursue (the
course) of the Tao do not adopt and allow them.
