Turning loose is never easy!  We love the familiar, the warm and comfortable, and the known.  The leap in the dark unknown, the uncertainty of what's out there which you can't see and can't comprehend, makes the future dark, foreboding, and fearful.  The budding high-wire artist has to overcome his fear of failure, of falling, of danger; otherwise, he never makes it to the big top.  Picture the trapeze artist, poised and ready to take the big leap. He swings out into space faster and faster, but then at some point, he's got to turn loose and fly through the air, reaching, stretching, towards the bar that swings towards him.
