Don't think of retiring from the world until the world will be sorry that you retire. I hate a fellow whom pride or cowardice or laziness drive into a corner, and who does nothing when he is there but sit and growl. Let him come out as I do, and bark.
Samuel JohnsonThe mind is seldom quickened to very vigorous operations but by pain, or the dread of pain. We do not disturb ourselves with the detection of fallacies which do us no harm.
Samuel Johnson
