My account of how I try to improve my writing:
2003: The certainty I could write a better book than the one I'd just finished.
2004: A first draft, a dismal contest score.
2005: A correspondence course.
2006: Another correspondence course and a form rejection letter.
2007: Armloads of books, on-line courses.
2008: A new first draft.
2009: Another rejection, weekly self-published newsletters.
2010: Another first draft, and a second draft.
2011: Critiquing, plotting, more writing, blogging, critiques. Determination to finish my WIP and submit by the end of the year.
