Listen to everything a man has to say about what he knows, but don’t let him advise you about what he doesn’t know. And usually he doesn’t know too much about what’s best for you.
Advice: The suggestions you give someone else which you hope will work for your benefit.
Advice is like castor oil, easy enough to give but dreadful uneasy to take.
What you do not use yourself, do not give to others. For example: advice.
In those days he was wiser than he is now; he used frequently to take my advice.
There is nothing which we receive with so much reluctance as advice.
Many receive advice, only the wise profit by it.
I am, at heart, a tiresome nag complacently positive that there is no human problem which could not be solved if people would simply do as I advise.
How is it possible to expect that mankind will take advice when they will not so much as take warning?
The only thing to do with good advice is to pass it on; it is never of any use to oneself.
