I find that drawing in my sketchbook always makes me feel happy and content.  It also makes me feel productive and purposeful, almost as if I have contributed something useful to the world.  As long as I let go of high expectations and enjoy my drawing practise, then I am always left with a really good feeling.  I can't think of a reason not to do something that makes one feel good.  Can you?
