At 20 a man is a peacock, at 30 a lion, at 40 a camel, at 50 a serpent, at 60 a dog, at 70 an ape, and at 80 nothing.
Be content to act, and leave the talking to others.
There is always time to add a word, never to withdraw one.
Never open the door to the lesser evil, for other and greater ones invariably slink in after it.
