Distance yourself and find a good study environment. Pack up and live on college or something. A good study environment, with other like-minded people will go a long way to motivating you to study. Get into a healthy cycle of exercise, study and games. I really think that the key to concentration is liking what you're doing. If you like and enjoy what you're doing, you're more likely to sit still and actually do it and do well. All you need is motivation, the rest just come naturally. How to start studying is one thing, how to study effectively is another. But most of the time if you're motivated to do well and to succeed and you want to do what you're doing, and you're surrounded by similarly motivated people and you dont have as many distractions around you, your work will be a breeze.
