Often, when I sit down and begin tapping away at the keyboard, I don't know where my initial thoughts will lead me. This approach, likened to throat clearing before making a speech, is an exercise recommended in a writing course I once took.
After a while, ideas take shape and, following several re-writes, they firm up and I understand the purpose or reason for writing the piece. If they don't, well it was just an exercise and is consigned to the wastebasket.
On other occasions, I plot and plan and storyboard and outline and then write. That usually happens for longer, or more complex works of fiction or non-fiction.
Knowing the intended purpose of the piece, its
market if for publication and the target audience then helps me when in the
self-editing mode.
When we pick up the
New Yorker or
National Enquirer, we know what to expect and how to receive it.
Describing the purpose of your work, whether intended for publication or not, and presented without the benefit of hardcover or magazine masthead, helps those reviewing or critiquing it to offer comments in an appropriate context.
