I have diagnosed ADD and most of your list is very familiar.

The way I things I usually end up binging through the entire book (or series) over several days. If, however, my reading spree is interrupted for whatever reason, I can just forget about what I was reading to the point where I return to it a year or two later to realize that I don't remember anything about it and have to restart.

The same effect tends to happen with any other project or habit I have. Painstakingly form a swimming habit and stick to it religiously for half a year? Doable, though extremely vexing. Then skip swimming for a week for some reason and the routine is just gone. I've had the opposite happen too though, where I just started doing workouts one day and consistently stuck to it for over 2 months with 0 effort (by which I mean I didn't have to struggle with choosing to do it. The actual physical exercise itself is a minor hurdle in comparison). Unfortunately, this habit also evaporated at some point.
