I have had dreams and I have had nightmares, but: If I were asked to give what I consider the single most useful bit of advice for all humanity, it would be this: Expect trouble as an inevitable part of life, and when it comes, hold your head high. Look it squarely in the eye, and say, "I will be bigger than you. You cannot defeat me."
