[MUSIC] I'm Professor Laurie Santos, a professor in psychology and cognitive science. And I'm excited that you're going to join me on this journey to learn a little bit about the science and also the practice of well-being. I started these lectures, here in Silliman College, right here in my home, to introduce a small set of students to the science of psychology. And we thought that it might be so beneficial to Yale students, we wanted to bring it to a bigger group, and that's where you come in. You get a chance to watch these short lectures on the science of happiness but also to think about how to develop these practices in your own life. That's why we've developed through this Center for Teaching and Learning a very cool new app. It's known as the ReWi app. It allows you to track all these practices that science has told us can increase happiness in your life, things like savoring more and gratitude and sleeping and exercise. As you watch the lectures, we encourage you to use the app to try to track these practices in your own life. I hope it'll make a difference, both in terms of teaching you about the science of happiness, but also giving you the tools you need to apply those practices in your daily life. We hope you enjoy it. Check out the lectures, thanks.
