I don't write as often as I read and edit other people's work, but I guess all of those interests were just close enough for me to want to develop each of them. Used to hate writing when I was younger. I'm not quite sure when the change happened; I just eventually felt like it was a productive way to build on ideas that I didn't want to ignore.
That said, if anyone should need a proofreader or an editor for their stories, feel free to ask. I'll be honest with you. This may make me seem harsh sometimes, but there's nothing that pleases me more than helping someone study and explore their craft. And that will always be my first priority when editing.
