The second trick is to leave the house. The writing life is full of contradictions. It depends on hours at a desk, but requires the author to be connected to the world. Setting out into the day like a useful member of society, helps.
The writing itself is hard to relate. It is a process of adding and taking away; deep thought and waking dreams; hard technical graft and the occasional leap of realisation. I drink lots of tea, chew gum and occasionally stand up and stretch. When I feel stuck, I put my head on the desk and try to reach that place between dreams and awareness, where the unconscious lives.
