I didn't know I was an autodidact until a few years ago when someone asked me if I was one. I looked up the word, told them I just learned what it meant, and responded yes. :D
The only thing that I really learned at University was how to learn. But I think I knew that before hand, because an alarming number of students in the first year, first foundational topic didn't know how to structure, write, or reference an essay. They didn't even know there were multiple methods of referencing.
The fun part was when different subjects called for different referencing standards.
Anyway, I digress. Remain lucid, I will continue to enjoy it.
