Stop the Block
Sometimes Creative Block expresses itself with a bunch of noise inside your head. Especially in this technologically oppressive age, the brain often finds itself overwhelmed with input. We lose sight of how many messages and flashing lights are constantly coming at us. The brain and the eyes are the organs that are constantly fielding that input (imagine a soccer or hockey goalie constantly bombarded by balls or pucks from the other team). Just in the course of an ordinary day the whole sensory system gets exhausted. So imagine what happens when you sit down with your sketch pad or your drafting table or your computer program and it's nine at night, and you decide you want to create something.
What your sensory system needs is a break. It needs you to STOP. You feel that fatigue (I know you do), but you've finally got a little time. The house is quiet. The kids are asleep. But the body is not a machine, and your mind lives all over your body. You can stave off a wrestling match with The Creative Block, by knowing when not to work.
Have you ever looked at a guitar at rest? Or a violin, or any musical instrument. They are beautiful. The shape, the wood, the detailing, all those aspects of a musical instrument make it a work of art even before it makes music. Well, you are just the same. Your whole physical being is a work of art; it has beauty and value even when at rest. You don't have to do anything. And, in fact, to get the most beautiful 'music' from your instrument, you need to give it a rest.
