Writer's Anonymus. Forum Roadblocks and Hurdles

Well, I'm setting this topic up as a fairly self-explanatory one. (Always better with fewer questions as to its purpose....)

When in the course of events as a writer, it becomes fairly common to come across... issues in continuing a written piece. This topic is there to discuss any particularities leading up to a writer's block, how to get over it, and general advice for writers.
