Jane Yolen in Take Joy: A Writer’s Guide to Loving the Craft (p.59) defines writer several ways but believes the best to be ‘one who writes’.
At first that sounds silly, but, after thinking about it, she makes perfect sense. For myself, writing is a compulsive act. I become anxious when I’m away from writing more than a day or two. Since, for me, stories come full blown. My fingers itch to set down characters, events and details as a part of my life. Are they good? Sometimes but usually after I work with them, go to critique groups and repeatedly edit them. I wish the definfition of a writer said,’one who writes well most of the time”. Then I’d feel better about what makes it to the page. Maybe next year!
