Ok, I'm not going to tell you to work like you sleep in the sense of how much work you get done out of your sleep time. Actually, there is a much more interesting perspective to that relation.
After watching this TEDx Midwest talk, I just confirmed what I always believed to be true but in a very well explained manner: Interrupting work is just like interrupting your sleep. With a 4 months old baby boy, I just realized how bad it is to your attempt to get some rest when you are interrupted 3 or 4 times throughout your night of sleep. Now think of how many times you get interrupted throughout your day of work, and you'll figure why it wasn't so productive. Really worth watching.
Now, just try and work like you sleep ;-)
