But the real fun of writing, for me at least, is the experience of making a set of givens yield. There’s an incredibly inflexible set of instruments—our vocabulary, our grammar, the abstract symbols on paper, the limitations of your own powers of expression. You write something down and it’s awkward, trivial, artificial, approximate. But with effort you can get it to become a little flexible, a little transparent. You can get it to open up, and expose something lurking there beyond the clumsy thing you first put down. When you add a comma or add or subtract a word, and the thing reacts and changes, it’s so exciting that you forget how absolutely terrible writing feels a lot of the time.
