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).

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 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.

The brain has an attentional mode called the "mind wandering mode" that was only recently identified. This is when thoughts move seamlessly from one to another, often to unrelated thoughts, without you controlling where they go. This brain state acts as a neural reset button, allowing us to come back to our work with a refreshed perspective. Different people find they enter this mode in different ways: reading, a walk in nature, looking at art, meditating, and napping. A 15-minute nap can produce the equivalent of a 10-point boost in IQ.
