Just think about it and write whatever comes to mind. Feelings, radioactive thinking? Maybe so. Just fantasize about the past, present and future. Think about the people and things in the past, then look at the people and processes now, and plan what to do in the future. And so on. This book should be a casual essay, just an inventory of some thoughts and so on.
