The lines of your coloring page are the rules you need to share with your team, share with them the boundaries. They are more likely to stay with in the lines if they know that they exist. Next by holding the work up for group and team acceptance they become their own self policing force. They can set self expectations and make constructive self criticism as well. The reward is acceptance and recognition from the team, an old saying is that a person can starve without any feedback, but only needs one good compliment to be filled to overflowing.
I was picking out some coloring books for my friends children when she informed me that she would like to get a couple of books too. This is a 30 something year old woman. She then began picking out colored pencils as well with a gleam in her eye like a kid in a candy store. She couldnt wait to get home and start coloring in her new books. She picked Barbie Doll, princess type books and methodically chose what colors she would use for the first picture.
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.
