If at first you don't succeed, destroy all evidence that you tried. Eagles may soar, but weasels aren't sucked into jet engines. Borrow money from pessimists - they don't expect it back. If at first you don't succeed, then skydiving definitely isn't for you. No one is listening until you make a mistake.
Success always occurs in private, and failure in full view.
Plan to be spontaneous tomorrow. A clear conscience is usually the sign of a bad memory.
