We write because it's good for our souls. Because, even if you don't like it at first the same way you disliked your mother's vegetable soup, it turned to something you craved in the coldest days. Because sometimes the pen is mightier than the sword and the only thing that will keep thoughts from escaping or devouring you is to take aim and a good swing. Because there are a little million word combinations to unlock our minds so others can take a glimpse at the mysteries we are.
Whatever, wherever, whyever, write. Simply because you are.
