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

"Ask advice only of your equals."

"Many receive advice, few profit by it."

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

"The true secret of giving advice is, after you have honestly given it, to be perfectly indifferent whether it is taken or not, and never persist in trying to set people right."

"Don't try to solve serious matters in the middle of the night."

"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."

"It seems that bad advice that's fun will always be better known than than good advice that's dull-no matter how useless that fun advice is."

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

"In giving advice, seek to help, not please, your friend."
