When you were 18, how concrete was your definition of well-being? Remember, this is a class being taught at Yale, whose incoming students are likely already high achievers. On top of that, a 10% admissions rate tells incoming students that they will simply have to keep climbing the ladder of GPAs, internships, varsity sports etc. for the next 4 years, and after that, for the rest of their lives.

I haven't taken this particular class, but I went through 4 years of college feeling like a failure if any one of the above "todos" didn't pan out, because it made me feel like I was closer to the bottom of the pile than the top. At that age, all you can see are the trees, not the forest

Looking back, it would've been nice to have had some perspective on what it's all for. Before you know it, you've graduated, and you can't go back and try to do things differently.

I looked into the course a bit more though and one of the first lectures addresses this preconception people seem to go into the course with in what the professor calls the "GI Joe Fallacy." She refers to it as "this mistaken idea that knowing is half the battle."

There will undoubtedly be behavioral practices or studies in positive psychology you may have come across before, but there is a difference in knowing those things vs. putting them to use through conscious, habitual effort.

I can't speak to how good the course is on that type of learned discipline, but it might be worth another go if you were interested enough to read the article.
