Ways to deal with writer's block:
I don't get the usual uninspired kind of writer's block; I always have ideas out the wazoo. The two obstacles I sometimes encounter are:
* I'm stuck on writing because the story/poem is missing a critical piece. I have learned to set it aside and work on something else, because that thing is going nowhere until I find the missing piece. Usually it takes a few hours or days, but I have some pieces that simmered for decades before getting finished.
* I feel like crap and I'm on a deadline, usually for nonfiction. Write a paragraph, go read fanfic or do something else pleasant to generate energy, write another paragraph. Or just a line if that's all I can manage. It is possible to level-grind through a whole article this way and produce something good.
