"Any fool can criticize, condemn and complain—and most fools do."
"Any intelligent fool can make things better and more complex... It takes a touch of genius and a lot of courage to move in the opposite direction."
"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."
