At 50, a man can be an ass without being an optimist but not an optimist without being an ass
Mark TwainIt is the will of God that we must have critics, and missionaries, and Congressmen, and humorists, and we must bear the burden. Meantime, I seem to have been drifting into criticism myself. But that is nothing. At the worst, criticism is nothing more than a crime, and I am not unused to that.
Mark Twain
