To practice any art, no matter how well or badly, is a way to make your soul grow. So do it.
As a growing writer, a halfway decent… um… draw-er? and a passable dancer, I can vouch for the truth of this statement.
Also, may I recommend some artistic cross-training? If you’re a writer, go doodle something. If you’re a painter, write down the thoughts that come to you while you work.
And if you’re a human being, dance.
