The most popular class in the history of Yale University is PSYC 157 -- "Psychology and the Good Life." It pretty much covers the science behind a positive outlook and how to change behavior and teaches students self-improvement.
And now, anyone in the whole world can take that class online for free.
The six-week seminar-based course is available for free on Coursera.
Which means, you can log onto a website, do the work -- and then brag that you’re “Yale-educated.”
