When you want to get good at something, how you spend your time practicing is far more important than the amount of time you spend.

We're all just a bundle of habits shaped by our memories. And to the extent that we control our lives, we do so by gradually altering those habits, which is to say the networks of our memory. No lasting joke, or invention, or insight, or work of art was ever produced by an external memory. Not yet, at least.

I have never been particularly good with languages. Despite a dozen years of Hebrew school and a lifetime of praying in the language, I'm ashamed to admit that I still can't read an Israeli newspaper. Besides English, the only language I speak with any degree of fluency is Spanish.

To attain the rank of grand master of memory, you must be able to perform three seemingly superhuman feats. You have to memorize 1,000 digits in under an hour, the precise order of 10 shuffled decks of playing cards in the same amount of time, and one shuffled deck in less than two minutes.
