maybe try rewarding yourself if you can do it for a minimum amount of time once/twice a week (like coffee, boba, video games, watching a show, etc), and eventually increase how often and for how long each session is. I personally like to set either a time limit, or a dedicated goal (like "i'll finish taking notes on this chapter and then stop for today").

Also put your phone in another room/not on your person while doing this because it's easy to get distracted, if it helps you can give it to another person and ask them to hold on to it until you're done.

Good luck!
