I agree 100% it's all about how you start your day. Facebook, Twitter,e-mail or Google Reader first thing is a no-go zone (and unfortunately, I too often drift there while having my morning coffee...). Interesting tip about waking up naturally - I set up the alarm clock, thinking I'm more in control that way - but will try your way for a few days :)

I find that getting some fresh air first thing in the morning sets me up nicely for work-mode. I learned that when I was looking after a friend's dog, and noticed the motivating effects of the morning walk.
