In the awareness wheel, there are five thoughts that you are aware of and your attention (the mask with a hole) concentrates its beam, daydream like, at none of them, just drifting in the centre. If you press on one of the tasks, your attention shifts towards it. The job gets smaller as your brain works on it. When it is complete, a slot is freed up and a new task pops in to take its place. At anytime you can choose not to focus on anything (daydream) or consciously focus on a thought.
