Waking Up Early, Key to Productivity?

How many of us love sleep? I guess many of us. I had a boss who said that he does  not care whether we sleep in but as long as we remain productive. The truth is productivity is synonymous with being awake.

Lately I have been struggling with waking up early. I cannot seem to get it right, yet I know that for me to remain productive, for all of us to be productive we must at best wake up way before the first bird chirps away into the morning.

Creativity and arising early are intertwined. How is this so?

Any views, any ideas on how to do this consistently?
