A wise man will make more opportunities that he finds.
Though a man is wise,
It is no shame for him to live and learn.
A clever person solves a problem. A wise person avoids it.
Ignorant men raise questions that wise men answered a thousand years ago.
Johann Wolfgang von Goethe
From the errors of others, a wise man corrects his own.
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.
All this worldly wisdom was once the unamiable heresy of some wise man.
Henry David Thoreau
A fool flatters himself, a wise man flatters the fool.
Edward G. Bulwer-Lytton
