"You remember the old Roadrunner cartoons, where the coyote would run off a cliff and keep going, until he looked down and happened to notice that he was running on nothing more than air?" "Yeah." "Well," he said, "I always used to wonder what would have happened if he'd never looked down. Would the air have stayed solid under his feet until he reached the other side? I think we're all like that. We start heading out across this canyon, looking straight ahead at the thing that matters, but something, some fear or insecurity, makes us look down. And we see we're walking on air, and we panic, and turn around and scramble like hell to get back to solid ground. And if we just wouldn't look down, we could make it to the other side. The place where things matter."
