A wise man is superior to any insults which can be put upon him, and the best reply to unseemly behavior is patience and moderation. By Moliere
Wisdom has a close relationship with sight-related words: foresight, insight, hindsight, reflection, enlightenment, visionary, etc. The wise person is able to see beyond the small issues and find a larger perspective; that is why they are so fascinating and useful. Telling your problems to a wise person will result in a solution that you might have not been able to think of, because you are too concerned with your own problems (which, in the scheme of things, are small).
