Live a happier and more fulfilling life.

In this ten week course, Professor Santos reveals what science says about how to improve your well-being.

We'll first learn about the misconceptions we have about what makes for a satisfying life. We'll then take a good hard look at the psychological biases and dumb features of our minds that lead us astray, biases that make it hard for us to see what makes us happy and cause us seek out the wrong sorts of things. We’ll then discuss what psychology research shows about what we really should strive for to live a happier life. We’ll then talk about how to put these new goals into practice.
