It's a Bit Like Doing a Crossword Puzzle

I just sit down. I put down notes after notes, about 400 pages of them, practically all of them utterly valueless, and then eventually once scene would clip onto another scene. It’s a bit like doing a crossword puzzle, you get the clue down and then you have to get the one across and unless the two fit you can’t get any further.
