Elon Musk recently did an AMA on reddit. Here are three question-and-response pairs that I enjoyed, including how to build knowledge.
He knows how to say I don't know.
Previously, you've stated that you estimate a 50% probability of success with the attempted landing on the automated spaceport drone ship tomorrow. Can you discuss the factors that were considered to make that estimation?
Musk: I pretty much made that up. I have no idea :)
Everyone has that one teacher…
I’m a teacher, and I always wonder what I can do to help my students achieve big things. What’s something your teachers did for you while you were in school that helped to encourage your ideas and thinking? Or, if they didn't, what's something they could have done better?
Musk: The best teacher I ever had was my elementary school principal. Our math teacher quit for some reason and he decided to sub in himself for math and accelerate the syllabus by a year.
We had to work like the house was on fire for the first half of the lesson and do extra homework, but then we got to hear stories of when he was a soldier in WWII. If you didn't do the work, you didn't get to hear the stories. Everybody did the work.
Finally, his answer on building knowledge reminds me of The Five Elements of Effective Thinking and the latticework of mental models.
How do you learn so much so fast? Lots of people read books and talk to other smart people, but you've taken it to a whole new level.
Musk: I do kinda feel like my head is full! My context switching penalty is high and my process isolation is not what it used to be.
Frankly, though, I think most people can learn a lot more than they think they can. They sell themselves short without trying.
One bit of advice: it is important to view knowledge as sort of a semantic tree — make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.
