GO LIGHTLY: Aldous Huxley was the renowned 20th-century intellectual who wrote the book *Brave New World*, a dystopian vision of the future. Later in his life he came to regret one thing: how "preposterously serious" he had been when he was younger. "There are quicksands all about you, sucking at your feet," he ruminated, "trying to suck you down into fear and self-pity and despair. That's why you must walk so lightly. Lightly, my darling . . . Learn to do everything lightly. Yes, feel lightly even though you're feeling deeply."
