Because I trust in the ever-changing climate of the heart. (At least, today I feel that way.) I think it is necessary to have many experiences for the sake of feeling something; for the sake of being challenged, and for the sake of being expressive, to offer something to someone else, to learn what we are capable of.
Inside of all of us there is the need and the desire to be heard, to have our innermost thoughts, feelings and desires expressed for others to hear, to see and to understand. We all want to matter to someone, to leave a mark. Writers just take those thoughts, feelings and desires and express them in such a way that the reader not only reads them but feels them as well.
