Even if you’ve heard that money or career success won’t necessarily make you happier, it’s still hard to resist the impulse to correlate your own well-being to external factors like those. Why are we so bad at predicting what will make us happy, and how can we figure out what actually does the trick?

These are just a couple questions you’ll be able to answer after completing “The Science of Well-Being,” a Yale University course currently being offered for free on Coursera. According to Lifehacker, the 10-week course consists of about two to three hours of reading and videos per week, and you can work at your own pace—so you can definitely take advantage of a free weekend to fly through a few weeks’ worth of material at a time, or postpone a lesson if you’re swamped with other work.

The class is taught by Yale psychology professor Laurie Santos, who will lead students through relevant research on how we’re wired to think about our own well-being and teach you how to implement that knowledge to increase happiness in your life. Since the coursework is task-oriented and the course itself is aimed at helping you build more productive habits, it’s an especially good opportunity for anyone who feels a little overwhelmed at how vague a goal to “be happier” can seem.

As for proof that this is definitely an undertaking worth 20 hours of your time, we’ll let the previous students speak for themselves: From 3731 ratings, the course averages 4.9 out of 5 stars.

Though the course is free, an official certificate to mark your completion—which you can then add to your LinkedIn profile—will cost you $50. Enroll on the Coursera website, and check out 23 other science-backed ways to feel happier here.
