Now for me, drawing is not only used in order to have fun... It is hard to teach a person how to have fun while drawing. Somehow I feel like drawing goes according to your mood; And not only drawing, but also coloring or painting...Usually people share their feelings to the colors, like if they are sad they use grey colore or any other dark colors, but when they're happy, they show that they are happy by using bright colors like yellow or light blue...etc...
