Librarians are more important than ever before ... are uniquely qualified to help all of us separate the digital wheat from the chaff, to help us understand the reliability of the data we encounter.

We need to take a step back, and realize that not everything we encounter is true. You don't want to be gullibly accepting everything as true, but you don't want to be cynically rejecting everything as false. You want to take your time to evaluate the information.

Ten thousand hours is equivalent to roughly three hours a day, or 20 hours a week, of practice over 10 years... 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.

When we have learned something, there's this thing called belief perseverance. Having learned something, we tend to cling to that belief, even in the face of overwhelming evidence to the contrary.

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.

Although I don't know Paul McCartney, a mutual friend told me that Paul was reading my book, This Is Your Brain on Music, and stopped after chapter two. McCartney said he was concerned that if he learned more about how he does what he does (as far as composing music), he may not be able to do it anymore!

We're making more and more decisions every day. I think a lot of us feel overloaded by the process.
