I suppose being a bit of an antisocial weirdo definitely honed my skills as a soloist. It gave me a lot more opportunities to solo lots of easy routes, which in turn broadened my comfort zone quite a bit and has allowed me to climb the harder things without a rope that I've done now.
To be clear, I normally climb with a rope and partner. Free-soloing makes up only a small percentage of my total climbing. But when I do solo, I manage the risk through careful preparation. I don't solo anything unless I'm sure I can do it.
I feel that a lot of human spirituality stems from the belief that we are unique and special in the universe, but maybe we are just what happens when there is proper temperature and proper distance from the right type of star.
