Woodworking requires a completely different kind of thinking and problem-solving ability than writing. With writing, you take a set of facts and ideas, and you reason your way forward to a story that pulls them together. With woodworking, you start with an end product in mind, and reason your way backward to the raw wood.

Kissing could have begun as a way of sniffing out who's who. From a whiff to a kiss was just a short trip across the face.

Our lives are the sum of our memories. How much are we willing to lose from our already short lives by … not paying attention?

Our lives are structured by our memories of events. Event X happened just before the big Paris vacation. I was doing Y in the first summer after I learned to drive. Z happened the weekend after I landed my first job. We remember events by positioning them in time relative to other events.

Over the last few millennia we've invented a series of technologies - from the alphabet to the scroll to the codex, the printing press, photography, the computer, the smartphone - that have made it progressively easier and easier for us to externalize our memories, for us to essentially outsource this fundamental human capacity.

The best memorizers in the world - who almost all hail from Europe - can memorize a pack of cards in less than a minute. A few have begun to approach the 30-second mark, considered the 'four-minute mile of memory.'

To improve, we must watch ourselves fail, and learn from our mistakes.
