I look at pictures to get ideas. Then I write down exactly the opposite of what I would do. This helps if it is late at night.
Night is a good time for inspiration.
I simply keep on writing when I meet a block. I just write without worrying about spelling or grammar. Soon I will find a masterpiece laying right in front of me. I go for a swim, the sound of the water is soothing and relaxing. Underwater I can think to myself, there are no interruptions, no intrusions.
