Winds of Winter Update

I know this is an old Thread but still, the whole book writing of Martin gets a bit on my nerves. He wanted to release "Winds of Winter" a lot earlier and now we are all still waiting for it. Maybe if you get famous you loose your muse or Motivation since, you don't have to write it anymore?

For some reason this all feels a bit like the books from "Robert Jordan - The Wheel of time" that book series wouldn't and wouldn'T end and later he died, without finishing it. Even if someone finished it a few years back, i can't chake the feleing this will happen to Martin.
