My experience of formal education was that it was a net negative. In my case my mum taught me to read before I started school and I was an avid reader as a kid. All my positive educational memories involved books, my parents or other adults outside of school and later the Internet.
The teacher I have the most positive memories of is the math teacher who told me I wasn't going to learn anything more in his classes and gave me permission to spend them in the library practicing for the exams instead.
Obviously I learned some things in school simply by virtue of having to spend so much time there as a kid. That doesn't mean I couldn't have had a better educational and life experience not going. The fact that I attended an elite university probably helped me getting some jobs early in my career but it wasn't a positive educational experience for me either.
