There are two things that come to mind that seem like opposite approaches. One is to find something you care enough about to actually concentrate on--some project you really want to work on, say. Your work ethic will be great as long as it's interesting enough to hold your attention. Then you need to find out how to sustain your interest when you finish, or get stuck or bored. The other way is to build a suite of habits to minimize, or at least de-emphasize, distractions, and to maximize the amount of time that you're focused on work OR not focused on anything else. You train your mind to enter a mode where either you're focused on work, or nothing at all. Since we generally don't like boredom we'll refocus on the work. This takes more discipline and long-term habits. This is the method that Stephen King advocates for in On Writing: you sit down every day at the same time and wait for the muse to come, and don't do anything else. I'll generally use a combination of these two strategies, and while I'm still more distraction-prone than I'd like, it generally works fine.
