When you get out onto a glacier that's the size of Northern Ireland and it's so vast, and you're standing on top of it and you can see forever, it's so pure and clear that you can see for miles and miles and miles. You really do think, "Wow, there is a god!" You feel very humbled.

I think the benefit of being a writer is that I'm looking for the subtext on the page, because all good writing has subtext. And as a writer, you look at the big scope of things, the big story, rather than just your individual story line, because I think it's important to know what you're in and how you fit into it.
