I do not learn from textbooks at all. I learn from playing. I played with all my toys "wrong" when I was a kid, or so I was always told. I always turned to the last chapter of a math book to see what I'm going to learn or to see if I could figure it out from what I already knew (what I would now call "first principles"). I took appliances apart and tried to put them back together. If I failed to do so my dad would help me put them back together, as long as I didn't tell my mom he was encouraging that behavior :) I watched my older sister play piano and learned the songs she was playing by ear, then asked her to teach me to read music.

This behavior often came out as rebellious or prodigy behavior in grade school but I don't think it's any of that. I think it was just a matter of giving a curious kid space to play and learn and grow. kids like me often don't thrive in rigid environments not because we don't like rules or think they shouldn't apply to us but because our brains just don't work completely linearly.

I'd wager that most kids actually learn better like this but it's not super efficient to cater to 30 different curious kids wanting to learn 30 different things.
