It could be a thousand things, distractions, worries; but very often I think what keeps a writer from finding the words is that she grasps at them too soon, hurries, grabs. She doesn’t wait for the wave to come in and break. She wants to write because she’s a writer; she wants to say this, and tell people that, and show people something else — things she knows, her ideas, her opinions, her beliefs, important things — but she doesn’t wait for the wave to come and carry her beyond all the ideas and opinions, to where you cannot use the wrong word.
