It had nothing to do with gear or footwear or the backpacking fads or philosophies of any particular era or even with getting from point A to point B. It had to do with how it felt to be in the wild. With what it was like to walk for miles with no reason other than to witness the accumulation of trees and meadows, mountains and deserts, streams and rocks, rivers and grasses, sunrises and sunsets. The experience was powerful and fundamental. It seemed to me that it had always felt like this to be a human in the wild, and as long as the wild existed it would always feel this way.

I was trying to find a new home in the world.

If there's one thing I believe more than I believe anything else, it's that you can't fake the core. The truth that lives there will eventually win out. It's a god we must obey, a force that brings us all inevitably to our knees.

I remember being absolutely rocked to my core by how profoundly I could love another human being.

One of the scandalous things I did was as I read them afterward I would burn them. I loved them, but for practical reasons I had to lighten the load. I burned favorites, like William Faulkner's "As I Lay Dying." There's a whole list in the back of my book. It's me,[Adolf] Hitler, [Benito] Mussolini, and Pol Pot. We're the book burners.

I made it the mantra of those days; when I paused before yet another series of switchbacks or skidded down knee-jarring slopes, when patches of flesh peeled off my feet along with my socks, when I lay alone and lonely in my tent at night I asked, often out loud: Who is tougher than me? The answer was always the same, and even when I knew absolutely there was no way on this earth that it was true, I said it anyway: No one.

I think the first thing - if you want to be a writer - the first thing you need to do is write. Which sounds like an obvious piece of advice. But so many people have this feeling they want to be a writer and they love to read but they don't actually write very much. The main part of being a writer, though, is being profoundly alone for hours on end, uninterrupted by email or friends or children or romantic partners and really sinking into the work and writing. That's how I write. That's how writing gets done.
