A lot of the people in history who I really admire lived before the hyperinformation age we're living in. Even if they were governing or solving problems in consequential periods, like the Civil War or the world wars or the Great Depression or the Cold War, they had a period of time and space to actually think, to be private and you read their biographies, and they had time to think about what was happening and how to respond.
