Earlier quoted context omitted.
This is called hyperfocusing (AKA the zone) and it's a typical characteristic of people with ADD. I have it pretty bad and I almost flunked out of school because I would spend all day reading enormous serial fantasy novels (wheel of time FTW!).
OT, but is there by any chance a series similar to wheel of time, or that captured you in a similar way, which you would recommend? Havent found anything quite like it, but that might be because of nostalgia and my fond memories of reading it as a teen.
Another recommendation would be Brandon Sanderson's Cosmere multi-series (Mistborn, Stormlight Archive), currently in progress, closer to WoT thematically.
