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.
Writing is self employment, so you can make your own schedule.
I don't set out to transmit a message. I don't write with a political point of view. There are no religious overtones. Looking back at my books, I can say, 'Oh, yes, it is there.' But it's not in my mind when I write.
I don't for one second think about the possibility of censorship when I am writing a new book. I know I am a person who cares about kids and who cares about truth and I am guided by my own instincts, and trust them.
I write books because I have always been fascinated by stories and language, and because I love thinking about what makes people tick. Writing a story... 'The Giver' or any other... is simply an exploration of the nature of behavior: why people do what they do, how it affects others, how we change and grow, and what decisions we make along the way.
