If you remember nothing else, remember this: Inspiration from outside one's self is like the heat in an oven. It makes passable Bath buns. But inspiration from within is like a volcano: It changes the face of the world.
I was an early reader, and my grandmother, who as a child had been forbidden to read by a father who believed books to be frivolous time-wasters, delighted in putting her favorite volumes into her grandchildren's hands.
I grew up in a very British family who had been transplanted to Canada, and my grandmother's house was filled with English books. I was a very early reader, so I was really brought up being surrounded with piles of British books and British newspapers, British magazines. I developed a really great love of England.
I had long ago discovered that when a word or formula refused to come to mind the best thing for it was to think of something else: tigers for instance or oatmeal. Then when the fugitive word was least expecting it I would suddenly turn the full blaze of my attention back onto it catching the culprit in the beam of my mental torch before it could sneak off again into the darkness.
