This obsession is a curious thing. Sometimes wonder about the merits of devoting so much of myself to a singular climbing objective. Much of the time it beats me down, leaves me hanging my head in despair. But then there are the moments that bring me to life. When excitement wells up inside my chest in a way that doesn’t happen in every day life. Today my fingertips were cracked and bleeding. I made no progress despite great conditions. Now I am on the ground and can hardly contain my excitement to get back on the wall. It’s a crazy rollercoaster and I owe my family and partners a great deal for encouraging me through it all.

I tend to pick objectives that I feel are safe because I know that, in the moment, I always go for it. I have some rules for myself, though: Look for the rock faces without a lot of loose rock. Always rope up on glaciers where there is even a slight chance of falling into a crevasse. No pure free soloing. Never climb below hanging glaciers.
