"Good advice is something a man gives when he is too old to set a bad example."

"Write down the advice of him who loves you, though you like it not at present."

"Many receive advice, few profit by it."

"Never take the advice of someone who has not had your kind of trouble."

"Never trust the advice of a man in difficulties."

"Some people like my advice so much that they frame it upon the wall instead of using it."

"Never advise anyone to go to war or to marry."

"The only thing to do with good advice is pass it on. It is never any use to oneself."

"People who ask our advice almost never take it. Yet we should never refuse to give it, upon request, for it often helps us to see our own way more clearly."

"There is no human problem which could not be solved if people would simply do as I advise."
