Move some part of screen time from phone/watching webseries or YT to easy reading, and do this regularly.
Like start with 15min to maintain atleast 30min a day. Do it at a fixed time of the day, like 30min before you sleep.
As for reading - goal is to find something super interesting and easy read to help with routine building - could be manga of your fav anime, fantasy fiction (Harry Potter, mistborn series and so).
Once you start reading, and maintain the minimum time daily, you will also see days where you spend more time, because you are hooked.
Overall this is how I am training. Underlining theme is fine deep engagement activity for consumption and use it to replace your passive consumption like reels, yt etc.
