In the 7-minute TED talk (below), Harvard psychologist Dan Gilbert illuminates some recent research on a phenomenon he calls the “end of history illusion,” where we imagine that the person we are today is the person we'll be until we die. But that's not the case.
The bottom line is, time is a powerful force. It transforms our preferences. It reshapes our values. It alters our personalities. We seem to appreciate this fact, but only in retrospect. Only when we look backwards do we realize how much change happens in a decade. It's as if, for most of us, the present is a magic time. It's a watershed on the timeline. It's the moment at which we finally become ourselves. Human beings are works in progress that mistakenly think they're finished. The person you are right now is as transient, as fleeting and as temporary as all the people you've ever been. The one constant in our life is change.
