"Writing is a concentrated form of thinking. I don't know what I think about certain subjects, even today, until I sit down and try to write about them. Maybe I wanted to find more rigorous ways of thinking. We're talking now about the earliest writing I did and about the power of language to counteract the wallow of late adolescence, to define things, define muddled experience in economical ways: Let's not forget that writing is convenient. It requires the simplest tools. A young writer sees that with words and sentences on a piece of paper that costs less than a penny he can place himself more clearly in the world. Words on a page, that's all it takes to help him separate himself from the forces around him, streets and people and pressures and feelings. He learns to think about these things, to ride his own sentences into new perceptions."
