Learning comes by reading and talking to people.
On talking to people:
“You must not overlook the importance of discussions with knowledgeable people.
I would say that is much more productive than absorbing or running through masses of documents.
Because in a short exchange, you can abstract from somebody who has immense knowledge and experience the essence of what he had gained.”
Learn to interview properly – how to prompt for information, how to develop the conversation and guide it towards the topics of interest – and you add to your toolbox of learning strategies.
