“One of my earliest memories is of sitting on a quay at the seaside watching a stick floating on the water. The waves were passing below me, under my kicking legs- I was still wearing short trousers- but, to my great surprise, the stick wasn’t carried along with them; it stayed exactly where it was, rising and falling as the waves rolled past. It seems to me now, looking back, that my life has been like that stick: time has rolled through me, like a wave, but I haven’t changed; I’ve stayed me. Even now, despite the invention of so many years, I feel I’m that same young boy, who can slip easily into sensations of wonder.”
