Somedays I feel certain and inspired and I run to the computer to work. Other days I feel flat and even doubtful that I have anything to say but I say to myself "Its the law", and go and sit down even if nothing comes. For me, its not inspiration but self discipline that gets books written. There are always surprised; when I feel inspired I may start writing and the thoughts disappear; on the other hand I may feel I have nothing to say and some amazing piece of prose comes out of me. The important thing is to show up, to sit down and to do the practice.
