I think Writer's Block hits for a lot of different reasons. And I don't think there's any one, single cure for it, either.
One of the things I've discovered about myself is that, as I stretch my writing muscles, my expectations start to rise. I want my next theme to be deeper and more profound than the last, my style to be more fluid, more perfect than what has gone before. And then - I freeze. I suddenly can't write anything, because everything I try doesn't meet those expectations.
The solution when that happens to me is to stop trying so hard. I purposely write something with every intention of just throwing it away. It doesn't have to be good, because it's not going to be a keeper. I'm just practising, just playing. Only when I stop trying to be "better" do the words start to flow again.
Don't know if that helps any. Probably not, since we all hit that wall for different reasons. But rest assured, we do all hit from time to time!
