Some people set very high standards for themselves and their writing. They think what they write is never good enough; they want to produce a perfect writing piece in one sitting, which is admirable but very unrealistic. Perfectionism drives us to ignore our achievements and drives us away from building our self-confidence.
Because of the constant pressure from our peers and professors, some people become very self-critical. This never ending stress to meet certain expectations reinforces the idea that they aren't “good enough” or aren't “smart enough” to do the assignment.
When we think of writer's block, we think of having a barrier that prevents the written expression of our creative thoughts. We think of procrastination as simply postponing doing something. In the novel Procrastination and Blocking: A Novel, Practical Approach (1996), Dr. Robert Boice describes procrastination as "opting for short-term relief through acts that are easy and immediately rewarding, while generally avoiding the thought of doing more difficult, delayable, important things" (pg. 19). He even stated that a writer's block can be defined as "getting stuck at a difficult transition point... usually because of paralyzing anxiety and uncertainty, often because the task will be evaluated publicly or because the taskmaster is distasteful." (pg. 19) Most fear works at the subconscious level and manifests itself in these two forms: procrastination and writer’s block. People that suffer from a writer's’ block find writing very stressful, so they have a higher tendency to push off any writing assignments that they might have.
