Eric is so right on in his post. I have often used and been very fond of that Nietzche quote, and I think it applies to many of us. You really don't know what you can do until you have to. I learned that bit about myself doing things that most people think they are not capable of, or are sure they would never actually do, years ago in some little crap hole of a place that I couldn't even pronounce the name of. I am stronger as a result of some of those things, and not proud of others. Cancer treatments were a similar challenge. This all translates to another truism in my life, which is that in many things - I do not change, until the pain of not changing exceeds the pain of the change itself. I think Eric should add the Nietzche saying to his signature, he clearly epitomizes it.
