If I didn't have children, I think my life would be a failure.

Every book I've written has been a different attempt to understand something, and the success or failure of the previous one is irrelevant. I write the book I want.

We feel a lot of pressure about looking silly or appearing weak, whatever that means, or being a failure. You have to keep in your head: what's the worst that can happen?

I'm living life as best I can - but I'm not exempt from failure and making bad choices.

Failure, it is thought, is what sells, and what people want to hear and read about. I am not so sure.
