The emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world-class expert - in anything. In study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, and what have you, this number comes up again and again…no one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.

It's getting harder and harder to know, when you find things on the Internet, what you can believe and what you can't.

The first forms of writing emerged not for art, literature, or love, not for spiritual or liturgical purposes, but for business--all literature could be said to originate from sales receipts (sorry).

For the artist, the goal of the painting or musical composition is not to convey literal truth, but an aspect of a universal truth that if successful, will continue to move and to touch people even as contexts, societies and cultures change. For the scientist, the goal of a theory is to convey "truth for now"--to replace an old truth, while accepting that someday this theory, too, will be replaced by a new "truth," because that is the way science advances.

The most fundamental principle of the organized mind, the one most critical to keeping us from forgetting or losing things, is to shift the burden of organizing from our brains to the external world.

We really are living in an age of information overload. Google estimates that there are 300 exabytes (300 followed by 18 zeros) of human-made information in the world today. Only four years ago there were just 30 exabytes. We've created more information in the past few years than in all of human history before us.

Love is about feeling that there is something bigger than just ourselves and our own worries and existence. Whether it is love of another person, of country, of God, of an idea, love is fundamentally an intense devotion to this notion that something is bigger than us. Love is ultimately larger than friendship, comfort, ceremony, knowledge, or joy. Indeed, as the Four Wise Ones once said, it may be all you need.
