I wasn't in a position that some other memoirists are, dealing with families who fed them meth, or kidnapped them, or did something that would make the writer not want to see that family again. I wanted to see my family. I wanted to celebrate them. I was proud of who we were, in the wilderness, floating down rapids or hiking over glaciers, and everywhere else.

After the age of seven, I began living between my dad in Alaska and my mother in Baltimore. Every three or four months, I would fly the 5,000 miles between the two. And having grown up in Alaska, Baltimore was astonishing.

After my parents divorced, my father remarried and my brothers were born when I was twelve and sixteen. I was thunderstruck at these kids. The "baby-ness" of them. Their toes. I had never been around babies before.

Often, I think that my brothers were the reason I didn't do something really stupid in my teenage years; I didn't want to disappoint them. Even though was I was pretty committed to disappointing everybody else.

Most kids who grow up in Alaska and spend a fair degree of time in the wilderness, grow up being pretty self-reliant. You have to be, in order to survive all the animals and cliffs and crevasses and rapids - at some point, your brain has to kick [out of] that childish daydream world and start making I-want-to-live decisions.

There was always some germ of joy, some little paramecium of happiness wriggling around, waiting for a chance to get out.

I turned what was a wonderful case of self-reliance into a case of self-exile. Which is not uncommon, I think, in people who grow really early and have to learn how to take care of themselves. They have trouble hinging their lives with anybody else.
