Sit and quiet yourself. Luxuriate in a certain memory and the details will come. Let the images flow. You'll be amazed at what will come out on paper. I'm still learning what it is about the past that I want to write. I don't worry about it. It will emerge. It will insist on being told.
I just have to proceed as usual. No matter what happens, nothing helps with the writing of the next book.
I'm more interested in writing than in performing.
I've been writing in notebooks for 40 years or so.
