You don't have to get a job that makes others feel comfortable about what they perceive as your success. You don't have to explain what your plan to do with your life. You don't have to justify your education by demonstrating its financial rewards. You don't have to maintain an impeccable credit score. Anyone who expects you to do any of those things has no sense of history of economics or science or the arts.

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.

Writing is part intuition and part trial and error, but mostly it's very hard work.

And if you're gonna be a writer, you just truly have to be a writer. You have to throw yourself into it and deal with the negative consequences of that. And there are negative consequences. I mean, there are. But, it's also true that you wouldn't be interviewing me right now if I had worked at the post office. You wouldn't. I would be still writing, but I wouldn't have gotten as far as I've gotten, because I wouldn't have had the time.

Nobody's going to do your life for you. You have to do it yourself, whether you're rich or poor, out of money or raking it in, the beneficiary of ridiculous fortune or terrible injustice. And you have to do it no matter what is true. No matter what is hard. No matter what unjust, sad, sucky things befall you. Self-pity is a dead-end road. You make the choice to drive down it. It's up to you to decide to stay parked there or to turn around and drive out.

I had to change. I had to change was the thought that drove me in those months of planning. Not into a different person, but back to the person I used to be—strong and responsible, clear-eyed and driven, ethical and good. And the PCT would make me that way. There, I’d walk and think about my entire life. I’d find my strength again, far from everything that had made my life ridiculous.

I was amazed that what I needed to survive could be carried on my back. And, most surprising of all, that I could carry it.
