Academic writers cannot get writer's block. Don't confuse yourself with your friends teaching creative writing in the fine arts department. You're not crafting a deep narrative or composing metaphors that expose mysteries of the human heart. The subtlety of your analysis of variance will not move readers to tears, although the tediousness of it might. People will not photocopy your reference list and pass it out to friends whom they wish to inspire. Novelists and poets are the landscape artists and portrait painters; academic writers are the people with big paint sprayers who repaint your basement.
