The advantage of the art coloring book based on "clinical art" is that it naturally turns on the concentration switch. Since I am not sure what I can do, I can concentrate on what I am doing without being conscious of what I am good at and what I am not good at. You will be surprised by the unexpected works that are born from unconsciousness! The time to concentrate without thinking about unnecessary things is truly extraordinary in everyday life. By the time the work is completed, you will feel refreshed!
