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.

I agree with the sentiment that it's probably more dangerous to believe some things that aren't so than to not believe something - you know, to believe in a lie.

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.

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

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.

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.

A song playing comprises a very specific and vivid set of memory cues. Because the multiple-trace memory models assume that context is encoded along with memory traces, the music that you have listened to at various times of your life is cross-coded with the events of those times. That is, the music is linked to events of the time, and those events are linked to the music.
