The quality of our attention determines the quality of our lives. You are what you choose to pay attention to and, crucially, how you pay attention. Looking back at your life, which memories bubble to the surface? Maybe it’s something big, like your wedding day, or maybe something small, that unexpectedly kind exchange with the person standing behind you on the ridiculously long post office line. Chances are, though, it’s moments when you were most attentive. Our lives are no less and no more than the sum of our most rapt moments.
