I watched this "60 Minutes" report about mountain climber Alex Honnold, who uses no ropes, with fascination. If he loses, he dies.
At workshops or conferences, I often use rock climbing as a spiritual metaphor relating it to risk factors. In climbing, you put a lot of faith in the rope and protection. That won't keep you from falling, but you don't hit bottom full speed.
I began serious climbing during a very dark time in my personal growth and development. In three or four hours, I could go through all of the trials and tribulations, risks and sometimes falls, but never crashing. I learned to trust the rope and protection and, most of all, my guides.
I've been injured a few times, but my life has never been at risk. I hired experienced and certified climbing guides, practiced what they taught and modeled. As my confidence in the guides and the protection increased, the more fun, joy and confidence.
This is the way it is in recovering one's health and fitness too. You have to do it yourself, but you don't have to do it alone. Trust the process and your guides, one day at a time.
