In old kids' cartoon films, there is often a chase sequence. The hero is running so fast, he steps over the edge of a cliff. But he continues to run forward with great success, until he suddenly stops and realises that there is no ground beneath him. Then we see shock on his face and he is shown plummeting like a stone. Perhaps you remember watching moments like this when you were young. Maybe you thought 'All he needs to do is keep running and not look, then he'll be fine!' In your life now, this really is all you need to do.
