If a man knows where to get advice, it is as though he could supply it himself.
Johann Wolfgang Von Goethe
Ninety percent of all human wisdom is the ability to mind your own business.
Robe rt A. Heinlein
One can advise comfortably from a safe port.
Friedrich Von Schiller
Harsh counsels have no effect; they are like hammers which are always repulsed by the anvil.
If we want to utilize in the proper way and to the fullest extent the products of a man's intellect, we must develop that part of man's being that is his heart and spirit.
Don't follow any advice, no matter how good, until you feel as deeply in your spirit as you think in your mind that the counsel is wise.
He is an incorrigible ass who will never listen to others.
When you talk, you repeat what you already know; when you listen, you often learn something.
To profit from good advice requires more wisdom than to give it.
Never seem wiser or more learned than the company you are with. Treat your learning like a watch and keep it hidden. Do not pull it out to count the hours, but give the time when you are asked.
One cool judgment is worth a thousand hasty counsels.
To accept good advice is but to increase one's own ability.
Many receive advice, only the wise profit from it.
None is so perfect that he does not need at times the advice of others.
He that gives good advice builds with one hand; he that gives good counsel and example builds with both; but he that gives good admonition and bad example builds with one hand and pulls down with the other.
Have you learned lessons only of those who admired you, and were tender with you, and stood aside for you? Have you not learned great lessons from those who rejected you, and braced themselves against you, or disputed the passage with you?
