At the beginning of last year, I joined the NSW Writers' Centre which is located on the site of the old Callan Park psychiatric hospital. I have done three courses with them now: one about a technique called 'show don't tell'; another on writing picture books for children; and today's course.
Today was not actually a course. It was the first in a monthly workshop group which critiques draft manuscripts. It was sooo worthwhile. It is astounding the different thoughts other people have about a story that the writer knows backwards, yet doesn't really know at all.
