One, and the most important thing:

Maintain a low-information diet. Many productivity gurus recommend keeping one’s information intake to a minimum. Just focus on what’s essential and ignore the rest. This is especially hard for web workers because the internet contains an infinite amount of information on a variety of subjects. Do you really need to know what Paris Hilton did last Saturday? Probably not, unless you’re a celebrity blogger.

Don’t get me wrong – being informed is a good thing. But too much of it can add to your personal tension and stress. When you take in more than you should, it consumes your time and attention, which can be better spent on relaxing activities. An hour of reading trivial RSS feeds could be used calling an old friend, catching up on your reading, or even napping.
