I often joke that I've just become a professional schmoozer. Like, nobody cares how well I can rock climb anymore. It just has to do with how well I can schmooze.
I think it's important I stay connected to every part of my personality. I play basketball. I rock climb. I paint. I'm a little bit scattered, but it's so I can convincingly play all these characters.
If you're climbing big routes that'll take you 16 hours, or, like, El Capitan, you have to take something like a big, robust sandwich. Climbing isn't like running or triathlons, where you have to constantly be eating blocks, gels, and pure sugar. Climbing is relatively slow, so you can pretty much eat anything and digest it as you climb.
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.
Higher productivity enables companies to increase sales without adding workers. Even if job markets tighten and wages rise, corporate profits can continue to climb as long as worker productivity is growing faster than overall wages.
