As someone with ADHD I self trained to stay on one thing until it's done, or I make a good progress. I make small breaks to look a bit online, respond to messages on the phone, eat, smoke. At about two hours I take a 10 minutes break. Than back to the stuff I am working. It required some discipline, but now it is easy. The harder is with context switches, calls, meetings, whether planned or not, colleagues asking for something, boss asking for something. Context switching kind of lowers my ability to be focused.
