For me, the favourite chapters have always been the last chapters in the books. I knew exactly how each book would end - and how the first chapter of the following book would begin. I knew I wanted to leave the readers with answers - and a bunch of new questions!

What the guys have learned is that whether you're preaching to one or 10,000, it really doesn't matter. That one person you touch may change the nation - could be the Billy Graham of Ethiopia.

In fact, writing for younger adults is tougher. They remember everything and if they spot a problem, they'll be sure to let you know.

All great literary works influence us as writers, not their stories as much as their storytelling ability.

Some stories wait their turn to be told, others just tap you on the shoulder and insist you tell them.

That is as true for fiction or non-fiction. The writer has to really know their subject. It is really important to remember that the readers are a lot smarter than the writer. Also, good writing has to do with rewriting. You will never get it right the first time. So you rewrite and rewrite again until you get it right. Until you, and the reader, will be able to visualize what you're writing about.

And once begun, change cannot be reversed.
