I used to have a hard time trying to concentrate at work. I would work for 9 hours a day but not get so much work done as I expect. So I kept looking for ways to fix it: stay away from the internet, track time working vs resting in minutes (like 50min work/10min rest), etc. It ends up it wasn't that much my fault. I worked on a pretty crowded office with lots of noise and where people would interrupt you multiple times. I'd get multiple emails in a day (multiple like 15, I've worked in places where you get 100s), and we'd have numerous meetings which weren't important. It all changed when I changed jobs. I've been working from home now: its all silent, I dont get any emails, only work 7 hours/day, and no meetings except the morning scrum, which hardly takes 5 minutes. When I spend time on the internet it hardly takes more than 10 minutes. I never have any issues going back to work, and get a lot done each day. So instead of focusing on self discipline, turning of internet, etc, I'd say focus on your working environment and project. That was the game changer for me, not internet, not self discipline, not 'get it done already'.
