When we’re stuck inside our heads, our experience of the world is two-tenths of a second behind the present moment. In practically any situation, social or physical, that’s a serious disadvantage. In every way that matters, two-tenths of a second is an eternity.
This is why a lot of people stress the importance of “living in the moment.” But I don’t like that phrase. It carries too many connotations of spirituality and abstraction that are too vague and esoteric to be of much help to many people.
Think about it: what is living in the moment? How can we characterize it, emotionally and cognitively? What are the mental circumstances of living in the moment: when does it “start” and “stop”?
