Tommy Caldwell and Keven Jorgeson are wowing the world and the climbing community with their mind-blowing attempt to free-climb the Dawn Wall of El Capitan in Yosemite. From the looks of it, Caldwell may have a book in him. Caldwell’s Instagram posts are nothing short of lyrical. Take this one, an ode to an inspiring frog:

At night on El Cap these frogs are our only companions. They emerge and effortlessly free solo around on the blank walls. This guy was 900 feet up and completely in his element. Keven and I are trying to summon our inner frog. We climb mostly at night and are doing our best to adapt to life on the wall.

I imagine a bunch of T-shirts with the slogan “Summon Your Inner Frog.” Hey, Tommy, wanna send me something for Fiction Attic?
