I often compare myself as a kid to my own grandchildren, who are around 11 and 14 now. That's the age kids usually read my book. And I remember myself, we'd gone through a world war. My father was an army officer so I was aware of what was going on. But I wasn't bombarded with images of catastrophe like many kids are today.

There's much more. There's all that goes beyond – all ... that is Elsewhere – and all that goes back, and back, and back. I received all of those, when I was selected. And here in this room, all alone, I re-experience them again and again. It is how wisdom comes. And how we shape our future.

Of course they needed to care. It was the meaning of everything.

Early on I came to realize something, and it came from the mail I received from kids. That is, kids at that pivotal age, 12, 13 or 14, they're still deeply affected by what they read, some are changed by what they read, books can change the way they feel about the world in general. I don't think that's true of adults as much.

Every 'no' means you are that much closer to a 'yes.

It is much easier to be brave if you do not know everything.

Writing is hard work, and fun, and requires you to keep your backside in a chair when you would sometimes like to put it elsewhere. So the only wisdom is the advice to keep at it, I guess.
