People talk about "Aha!" moments. What about "I've stopped caring!" moments? Can you recall a particular instance, in writing or in life, where stopping caring was the cure? Where *letting go* jettisoned you forward, helped you get unstuck?
That's a fantastic question! I can't think of a particular instance in writing, but I have, in the past, gotten to the stage where I've been convinced what I was writing was rubbish. But deadlines dictated I needed to carry on anyway. Fortunately, once I got to the end and read it back, it wasn't actually terrible at all!
