I'm lucky in that I was approached by a French book publisher to write a non-fiction book on an extreme sport. The problem is, there's no deadline and I don't know how long the manuscript should/could be. I haven't read books published by that publisher yet, but that's happening next week. I asked about tone of voice and the answer was, it's all up to me. So, my voice it is and I love that, but I need more. I usually work best under pressure or with deadlines. I'm one to write in spurts, not in a steady disciplined stream, and that's probably what I need.
Would love some tips from published non-fiction writers on their creative process and how to keep motivated. Based in London, if there are any non-fiction writers groups that would be helpful.
