Never trust the advice of a man in difficulties.

It is very difficult to live among people you love and hold back from offering them advice

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

Ask advice only of your equals.

Please give me some good advice in your next letter. I promise not to follow it.

Don't give advice. It will come back and bite you in the [butt]. Don't take anyone's advice. So, my advice to you is to be true to yourself and everything will be fine

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

Advice is what we ask for when we already know the answer but wish we didn't.

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