The story of Luhmann's prolific work really is fascinating. He self-taught himself to the point he had the work for his PHD already in place before someone said "Hey, you should be a prof". Then he just went back to his cool note-taking system and drew on what he already had.
Imagine if school children were taught that system from an early grade? To not just memorize facts to get grades but to integrate facts into their knowledge base and find connections between their learning. I think the results would be amazing.
