More information to follow in due course
That depends. Sometimes I look for something to keep me busy in the hours, like doing some art work, listening and dancing to music, catching up with my friends and playing games or helping my parents do some work around the house. When I focus on a simple thing, the ideas quietly work by themselves and later I can just return to my desk and start writing. If I cannot think of anything for a long period of time, I intensively work on a new topic or do some research.
