"Be thankful for your stupid mistakes--for they usefully remind you of your natural incompetence and need for help. And that reminds you of your total dependence on God's guidance and direction, in order to do anything useful or worthwhile. And that brings your mind back to where it should have been in the first place, from which it had wandered through the weakness and deceptiveness of the flesh. A 'successful,' self-satisfied, self-dependent man is a man totally out of touch with the eternal realities which we must ever keep in mind if we are to please God and be His. Be thankful for your stupid mistakes: they're wonderful eye-openers."
