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.

We can be skeptical, suitably skeptical, and we can trust news outlets, some more than others.

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.

No other species lives with regret over past events, or makes deliberate plans for future ones.

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.

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!

The most important, the longest lasting, the strongest emotional, and the most practiced memories are the ones that are embedded the deepest in the brain, and because we have retrieved them so many times previously, they are the most able to be retrieved. We all hear about people who can remember their youth, their phone number, or street address from 70 years ago, but they cannot recall what they had for breakfast. The memory of this morning's breakfast wasn't rehearsed, and wasn't very important, so it fades away quickly.
