A word to the wise isn’t necessary, it’s the stupid ones who need advice. The use of this quote in public speaking is to say that if you are asking for advice, then you are probably not doing something that people would be surprised by. If you are asking for advice, then your words should be transparent and there shouldn’t be anything hidden in the message.
