This is going to sound contrived, but I don't get writer's block. At least I have not to this point. Now that I say that, I'll probably be struck by chronic writer's block.
Before I start to write a story, I already have the entire plot in mind. Not every tiny detail, but the general flow, and I take opportunities to improvise and improve along the way as I create the story.
There are times when I may have difficulty writing a particular scene, but in that case, I typically take a long walk -- something over a mile -- and by the time I return, I have it sorted out. Worst case, I skip the troublesome scene and move on to the next one, then come back... but I've only had to do that a handful of times.
So, I think the takeaway is: plan ahead. With a general roadmap, you'll always know your general direction, and that solves a lot.
