Now, ladies and gentlemen, I’d like to share with you the psychology of your future selves in today’s talk.
    At every stage of our lives, we make decisions that will profoundly influence the lives of the people we’re going to become, and then when we become those people, we’re not always thrilled with the decisions we made. So young people pay good money to get tattoos removed that teenagers pay good money to get. Middle-aged people rush to divorce while young adults rush to marry. The question is, why do we make decisions that our future selves often regret?
    Now, I think one of the reasons is that we have a fundamental misconception about the power of time. Every one of you knows that the rate of change slows over the human lifespan, that your children seem to change by the minute while your parents seem to change by the year. But what is the name of this magical point in life where the speed of change suddenly alters? The answer, it turns out, for most people, is now, wherever now happens to be.
    Let me give you some data to back up that claim. So here’s a study of change in people’s personal values over time. We asked thousands of people. We asked half of them to predict for us how many their values would change in the next 10 years, and the others to tell us how many their values had changed in the last 10 years. And this enabled us to do a really interesting kind of analysis, because it allowed us to compare the predictions of people, say, 18 years old, to the reports of people who were 28, and to do that kind of analysis throughout the lifespan.
    Here’s what we found. First of all, change does slow down as we age, but secondly, it doesn’t slow down nearly as much as we think. At every age, from 18 to 68 in our data set, people vastly underestimated how much change they would experience over the next 10 years.
    The bottom line is that time is a powerful force. Only when we look backwards do we realize how much change happens in a decade. 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 temporary as all the people you’ve ever been. The one constant in our life is change.
    Thank you!
