@matigo If by "school" you are referring to compulsory education as it is known in most countries, I don't know how much I can argue with you. I certainly don't remember much from my days in grades 1–12.
I've thought about that lately, how so very little of what we learned in school seems to stick with us as we get older, and how our life experiences outside of compulsory education and our hobbies or interests tend to stick with us much more. There is the embarrassment I will always feel in not being able to help my daughter with her homework of learning facts and formulas, because I have all but forgotten most of that. On the other hand, my language skills were probably reinforced not in school per se, but by reading books and being interested in them. Math and the sciences (except for astronomy) never stuck with me, so I suppose that compulsory education failed me in that respect too.
The people who became teachers who genuinely wanted to be teachers probably eventually learn that they can teach in other settings besides traditional schools, and have a potentially bigger impact.
