I'm rarely blocked. Having a disciplined writing schedule helps. You just keep going. But I do find myself confused or undecided at times about choices, particularly plot alternatives. I don't hold with the advice of simply taking one to see where it leads and being willing to scrap that whole scheme if it leads to the wrong place. No, I ask my subconscious the question, then I get up and do something else. And sleeping on it often works. So does climbing into the shower. Ask the question, and sooner or later, but probably not right away, the answer will present itself.
