The concept behind each of these lessons was further elaborated with climbing experience and a real life example in his book.
Fallure, an invented jargon for climber may be, is a bit of wordplay derived from a decision that rock climbers make if they know they cannot complete the route they have chosen for a climb. They allow themselves to fall, knowing that the bolts attached to the side of the rock face through which their climbing ropes are threaded will break their fall. In fallure, a climber still fails to get up the route, but he or she pushes to the ultimate limit. Fallure means a climber made a commitment to make the ascent, despite the odds.
