Avoid editing as you write your first draft. Simply create—let it freely flow. View your first draft as the beginning of the beginning. It is akin to a sculptor placing a block of granite on his or her studio's floor. The work of art, given the idea is well-formed and planned, is ready to take shape. There is much more to say about this, but for now, let this suffice.
