I've never read an full adult book in my whole life and am proud of it! My attention span is that of a toddler's, which I can admit proudly as well, yet I've self-taught how to code, 3D printers, chess 1800 Elo just playing never studying, 3D software, psychologically—which seems to be at a higher tier of understanding than most educated people (not in all areas though I admit)—maths, physics, found new pattern in 3x3 magic square of squares, which inversed is a new emergent pattern, art, poetry, ideas for AI advancement.
My 2 year old daughter counted to 10 on walk to local shop yesterday, she's equivalent to a 4 year old at half the age, because I listen and understand her, with 2 way commination and showing I understand her even though she couldn't say the right words allowing me to teach her quickly because I cared to understand!
I'll stop there for now, books mean nothing compared to my ability to understanding without any knowledge.
Also I probably need grounding now, but all the above is true! and many other smaller things that I kind of find irrelevant.
