Could you elaborate on that a bit more? I have ADHD and am very interested in anything about it but have never heard anything like that.
- Stop drinking coffee - Get rid of Social media notifications and stuff - Actively aim to bore yourself when the day starts, don't look at the phone. - Then suddenly you'll notice that your brain is dying to do something interesting, so much that you'll start reading toothpaste's label while brushing your teeth. Start building up stories about how that label came to be (and all that is ok, as long as it isn't jumping around). - Then open your computer and the task you want to do, and find yourself be VERY INTERESTED in doing that.
However, the OP is talking about distractions which cause ADHD to be present, something I have not heard about.
