The more we remember, the better we are at processing the world. And the better we are at processing the world, the more we can remember about it.

If you want to make information stick, it's best to learn it, go away from it for a while, come back to it later, leave it behind again, and once again return to it - to engage with it deeply across time. Our memories naturally degrade, but each time you return to a memory, you reactivate its neural network and help to lock it in.

To the extent that experience is the sum of our memories and wisdom the sum of experience, having a better memory would mean knowing not only more about the world, but also more about myself.

Growing up in the days when you still had to punch buttons to make a telephone call, I could recall the numbers of all my close friends and family. Today, I'm not sure if I know more than four phone numbers by heart. And that's probably more than most.

Memory is like a spiderweb that catches new information. The more it catches, the bigger it grows. And the bigger it grows, the more it catches.

Truman Capote famously claimed to have nearly absolute recall of dialogue and used his prodigious memory as an excuse never to take notes or use a tape recorder, but I suspect his memory claims were just a useful cover to invent dialogue whole cloth.

How much are we willing to lose from our already short lives by losing ourselves in our Blackberries, our iPhones, by not paying attention to the human being across from us who is talking with us, by being so lazy that we're not willing to process deeply?
