It's like the trapeze artists in the circus. They swing back and forth hanging on to the trapeze bar. But if that's all they do, there's no thrill for the audience. It's that split second when the artist lets go of the bar and is "flying through the air with the greatest of ease" that makes the audience stand up and cheer. It's the letting go, taking the risk that the other trapeze will arrive at just the right moment, that gives life excitement.
Sure, the danger of falling is always there. But the guy who clings to the trapeze bar and never lets go cannot know the exhilaration of the guy who releases himself to take the risk. He may live longer, but he won't live better.
