There's no such thing as writer's block. Writer's block is real, but it does not exist. What it really is is misnamed 'I have a fear of bad writing. I have a fear of what the world will say when it encounters my bad writing.' And the way through is to do your bad writing. You don't have to ship it to the world, but you have to do the bad writing. And bad writing, over time, if you do enough of it, can't persist. Good writing will slip through.
