Writing is transcendental. It is a form of expression, a form of art that you can take anywhere. That you can do anywhere. It poses the deepest questions in the universe. It generates emotion. It elicits empathy, promotes learning, creates an intellect you simply cannot get from any other medium. For me, it is air.
