For John was running, and this was terrible. Because if you ran, time ran. You yelled and screamed and raced and rolled and tumbled and all of a sudden the sun was gone and the whistle was blowing and you were on your long way home to supper.

People ask me to predict the future, when all I want to do is prevent it. Better yet, build it. Predicting the future is much too easy, anyway. You look at the people around you, the street you stand on, the visible air you breathe, and predict more of the same. To hell with more. I want better.

I never consciously place symbolism in my writing. That would be a self-conscious exercise and self-consciousness is defeating to any creative act. Better to get the subconscious to do the work for you, and get out of the way. The best symbolism is always unsuspected and natural. During a lifetime, one saves up information which collects itself around centers in the mind; these automatically become symbols on a subliminal level and need only be summoned in the heat of writing.
