Some years ago I had the privilege of hearing Bernard Cornwell speak at an HNS Conference. He insisted that this is a business and there is no such thing as writer's block anymore than there is "dentist's block." He asked us to imagine showing up for a dental appointment to be told by the nurse the dentist wasn't feeling up to filling teeth that day. That helped me immensely. During work hours--albeit truncated by other occupations--I sit in my chair and I write. No excuses.
