The next step is simply to unplug the Internet. You can either disconnect the Internet connection or unplug the Ethernet cable to your computer. This is definitely a drastic but effective method of staying on top of things. This is even easier if you've decided to opt for a laptop as your main computer. Going offline will reduce your access to any number of online distractions, from Facebook status updates to pesky emails. You simply disconnect from your WiFi home network and you're done. While we think that this will work extremely well for some people, it might not work for everyone, as many students and workers have to do research online for their assignments.
Another simple strategy involves switching browsers when you want to get work done. For example, I use Firefox as my main browser. This is the browser with which I access my email and all of my RSS feeds. There are usually 5 to 10 tabs open at any time. When I get ready to do some real work, I close Firefox and open Chrome. There are no saved tabs on this browser, and once I check up on a fact or detail, I immediately close the tab and/or the browser. There is no Facebook tab or Twitter tab open, and I never check my email with Chrome.
While this won't work for everyone, it will work for people who absolutely need the Internet to stay productive and have the willpower not to log onto Facebook every few minutes to see what's up with their friends. If you are in the latter category of people, just switch off the Internet to get things done. Another tip would include on scheduling these offline periods (1 or 2 hours when you need them) to make them even more productive. You can get very productive when you are no longer distracted.
