I find audiobooks help a lot for being able to finish books nowadays
When I was a kid I could just devour books if I was interested in them otherwise it’s was a struggle. Straight up to the point of forgetting to eat and whatnot.
Audiobooks though allow me to do things while listening which is cool.
I only got diagnosed with ADHD about 6 months ago as an adult so getting those good habits is still a struggle but way easier with meds as long as I don’t get distracted before they kick in.
