I'm working on theory that we all desire to be teachers, though definitely not teachers in a school classroom. I think the desire to share what we've learned is part of the process of learning, maybe a validation step. There can be lots of factors affecting one's situation, but for the most part life can be rearranged to accommodate things like teaching. Maybe the reason we don't run out and share what we've learned is because we adults don't feel like we know anything worth sharing.
Lately I'm reading the ancient philosophy texts and thinking about what it was like to learn back then. Plato had Socrates (who didn't believe in writing!) and he had to compete with other younger students for his favor. This meant not only participating in the conversations available but also making himself available to them. Can you imagine how different the learning experience would be if teachers just made themselves available from 9am-3pm every day, and students could choose to fill all or none of their time in their company? Like if spontaneous moments of brilliance came about when something like a high school german instructor bumped into a legendary cognitive science professor and together, they discovered a new idea at the intersection. And teachers and students (who made the effort to be there) could have been there to witness the whole thing. To see the joy of learning something new, on the two faces who only together made it possible. And to themselves learn something new from it. It's amazing stuff when we let it be.
The situation in which we find ourselves today, both ends of the dialogue are confused about what to do. The students aren't sure what to seek out, and they seem to rely more on luck and fate to assemble an understanding of the world for them. This makes me think no one is telling them what they're capable of, or about all of the lifetimes of enjoyment they can find in the world without spending a cent, only their time. There are millenia of human histories to explore and help them find their place, but the teachers on the other end are seeing the lack of interest in their methods and are taking it personally.
We need a much more flexible perspective on education, and I think a big part of that is becoming great teachers in our own lines of work like you're doing. We simply cannot put "learning" in a box and on a store shelf and expect the next generation to just pick it up. This is a life-long journey for all of us, and it can be a life-long joy if we help others see and feel the value of living!
