I don't get what I think of when I hear "writer's block" (knock on wood!). I have drawers and notebooks crammed with ideas, character sketches, and so forth. My problem has never been that I lacked ideas to fill my writing time, but rather that I will ultimately leave a great deal of work unfinished no matter how long I live. My big dilemma is what I should work on next. When I get stuck in a story, I just power through. I keep writing even if it's crap until I get to the next part of the story that's clear in my mind. Once I complete the first draft, no matter how bad it is, I can then go back and fix what's broken.
