If a man knows where to get good advice, it is as though he could supply it himself.
No man is so foolish but he may sometimes give another good counsel, and no man so wise that he may not easily err if he takes no other counsel than his own. He that is taught only by himself has a fool for a master.
A man's pride can be his downfall, and he needs to learn when to turn to others for support and guidance.
When you seek advice, do not withhold any facts from the person whose advice you seek.
A second opinion never hurts, not only in medicine, but also in politics.
You know how advice is. You only want it if it agrees with what you wanted to do anyway.
