My peak? Would I even have one? I hardly had had anything you could call a life. A few ripples, some rises and falls. But that's it. Almost nothing. Nothing born of nothing. I'd loved and been loved, but I had nothing to show. It was a singularly plain, featureless landscape. I felt like I was in a video game. A surrogate Pacman, crunching blindly through a labyrinth of dotted lines. The only certainty was my death.

You got to know your limits. Once is enough, but you got to learn. A little caution never hurt anyone. A good woodsman has only one scar on him. No more, no less.

Nothing so consumes a person as meaningless exertion

So the fact that I’m me and no one else is one of my greatest assets. Emotional hurt is the price a person has to pay in order to be independent.

I can't imagine how American readers will react to a novel, but if the story is appealing it doesn't matter much if you don't catch all the detail. I'm not too familiar with the geography of nineteenth century London, for instance, but I still enjoy reading Dickens.

Who can really distinguish between the sea and what's reflected in it? Or tell the difference between the falling rain and loneliness?

For me, running is both exercise and a metaphor. Running day after day, piling up the races, bit by bit I raise the bar, and by clearing each level I elevate myself. At least that’s why I’ve put in the effort day after day: to raise my own level. I’m no great runner, by any means. I’m at an ordinary – or perhaps more like mediocre – level. But that’s not the point. The point is whether or not I improved over yesterday. In long-distance running the only opponent you have to beat is yourself, the way you used to be.
