Another ADDer here. I have two modes of operation: hyper focused or not. Things that require focus, like deep reading mean I need to switch operating modes. I have oodles of ways to address this issue so I only chose a few. Maybe one helps.

Ways I do that: 1. Be really interested in the content — not sure if this works with a non add brain, but it really doesn’t matter where I am, if it’s interesting I’ll jump right down that rabbit hole. Not sure that helps you but maybe can create some parameters for experimentation (like is there a pattern with your interest level and if so how can you mitigate that) 2. Meditation - specifically working with the breath. It takes 30s-3min for me to reboot my brain between tasks. Not much of an investment and in my experience it works. 3. Printing stuff out — i find it much easier to read deep if I have it on paper 4. Copying into an editor and editing — this is my goto for boring reads because it uses a different part of my brain that reading alone 5. At the end of each paragraph I ask myself “what was the point of that?” This is a habit that takes time to develop. At first you may get through an entire article without asking but eventually you can catch yourself sooner.
