Writer's block is a condition, primarily associated with typing, in which an author loses the ability to produce new work. The condition ranges from difficulty in coming up with original ideas to more extreme examples in which some "blocked" writers have been unable to work for years, and some have even abandoned their supposed lifelong careers. Throughout history, writer's block has been a documented problem. Professionals who have struggled with the affliction include author F. Scott Fitzgerald and pop culture cartoonist Charles M. Schulz. Writer's block can manifest when a writer views their work as inferior or unsuitable.
