A few lessons I learned after reading Moonwalking with Einstein by Joshua Foer:
"Practice makes perfect-only if it's the right kind of concentrated, self-conscious, deliberate practice";
"How we perceive the world and how we act in it are products of how and what we remember..."
"...our ability to find humor in the world, to make connections between previously unconnected common culture:all these essentially human acts depend on memory."
All these seem so obvious but they are not.
