If you find yourself wasting too much time puttering around on the Web instead of getting actual work done, services like RescueTime and Facebook Limiter temporarily lock you out of the sites you procrastinate on the most. Browser add-ons are another quick way to keep focused. For example, LeechBlock for Mozilla Firefox and Productivity Owl for Google Chrome let you add the URLs of the sites where you waste the most time, and will deny you access to those places when you try to sneak a peek instead of working. Both add-ons are free, but their creators gladly accept donations.
