An extremely vivid memory from childhood—probably about seven or eight years old. Waking up and coming downstairs with an absolute, unshakable conviction that what I wanted to do with all of my spare time for the next few months was to build near-full sized fairground rides in our back garden. I don’t know where this came from; prior to that point I had no especial interest in fairground rides, beyond the annual visit to the Goose Fair. I wanted to go into the garage immediately and start measuring pieces of wood, making designs, etc. It took my parents a couple of hours to dissuade me that doing this was utterly impractical, against my deep, passionate protestations. Truly I cannot think of anything before or since that I wanted to do with such utter conviction.
