There isn't a single day I don't do some writing -- if you don't, you won't have a book. When you're self-employed it is very easy to burn away your time instead -- answering e-mails, surfing the Internet, or hanging out with friends. You really must have the discipline to sit down and write every day. Most of what I am writing is living in the back of my head or in my subconscious. I find if I write every day, my subconscious will do the job for me.
