Very useful pieces of advice here, good job with this article! I would add that it's very important to work on one's discipline, as it is the basis for all stated above. For instance, if you work in the social media field and you're basically all over social networks all day long, it's very difficult keeping yourself away from distractions such as chat messages or surfing the news feed. Kinda paradoxical :)) This is where a strong discipline should step in.
