Disappointment Can do a couple things. It can drop you into a giant sucking sinkhole of depression, a place you have to fight to climb out of. Or it can trigger an epic mania to overcome the odds and transform failure into success. Say you swing as high as the chains will take you because you seek the thrill of flight, and on the up- kick, you lose your seat. Injury is likely. But if you worry about falling down, and never chance "up," the sky will remain forever out of reach.
