Remember those days when you worked on your coloring books, and had to keep within the lines? Ever felt stressed as a child just making sure you didn't go beyond those dark lines with your crayons? Now, you don't have to be stressed - and in fact, you can have a lot of fun with coloring books!
Coloring books are actually therapeutic: they allow you to play again, to be a kid again, to be young and relax. All you need are as many crayons as you want, and the coloring book of your choice. Pick a nice spot where you can color comfortably without people passing by and wondering if you have your head on straight.
Now, color - and don't be afraid to use weird colors or go past the lines. Just color and don't think. Oh, and breathe deeply - take this chance to stay sane by going a bit insane.
