Concrete - pg. 151

When we have sentences in our heads we still can't be certain of being able to get them down on paper, I thought. The sentences frighten us; first the idea frightens us, then the sentence, then the thought that we may no longer have the idea in our heads when we want to write it down. Very often we write down a sentence too early, then another too late; what we have to do is to write it down at the proper time, otherwise it's lost.
