Coloring in a Doodle Book. You can do this very effectively by getting an artists sketch pad. This is a pad of blank sheets of paper used by artists to plan their paintings or creative work on, much like a writers rough draft. Once you have your pad, take a pencil and start to doodle. Make lines, circles, shapes, what ever at the time makes you feel good. Then color in the spaces within the doodles. Even if you think you are not a very creative person you will feel productive and relaxed after a few doodle your noodle calming sessions.
After watching how mesmerized she was while filling in the images with her newly sharpened pencils, I decided I wanted to color as well. Although the images I colored werent exactly inspirational to me, I enjoyed the experience overall. The next day, I decided I wanted to get my own coloring book with a new set of colored pens. I bought a book full of pictures of mandalas (a circle with complex designs in it). The designs were beautiful and I could imagine them once I filled them with color.
