Phillip Pullman

You don't win races by wishing, you win them by running faster than everyone else. And to do that you have to train hard and strive your utmost, and sometimes even that isn't enough, because another runner just might be more talented than you are. Here's the truth: if you want something, you can have it, but only if you want everything that goes with it, including all the hard work and the despair, and only if you're willing to risk failure. (That's the problem with Karl: he was afraid of failing, so he never really tried.)
