Writing music is hard

Writing music is hard.  I love doing it but I have yet to write a piece where I did not have significant writer's block.  What I often do is wakeup early and spend an hour or so working on a piece before starting work.  I have been writing and playing music for a few years and it is still hard each time.  It really is 10% inspiration, 90% perspiration. Enough so that I stopped and wrote a blog entry about it.
