John Ruskin

Every day we have plenty of opportunities to get angry, stressed or offended. But what you're doing when you indulge these negative emotions is giving something outside yourself power over your happiness. You can choose to not let little things upset you.

As so many writers know, the experience of creating an imaginary world is closer to dreaming than it is to normal, grit-your-teeth work. It's preconscious rather than conscious. Ideas fall into your head, and the book writes you, rather than the other way around.
