But, in Harvard's hallowed halls, and in other schools, an unusual class tries to put a smile on the face of every student.
The song "Don't Worry, Be Happy" comes to mind.
As The Early Show correspondent Melinda Murphy reports, "Positive Psychology" is one of Harvard's most popular classes.
Basically, it's s class in how to be happy, taught by Tal Ben-Shahar.
"You an absolutely teach people how to be happier," he tells Murphy. "While you cannot teach a grouch to be Pollyanna, you can certainly increase people's levels of optimism and happiness."
Seems he's onto something, says Murphy: Some students she spoke to say it's more than just a class, it's a prescription for life.
Everyone in one group at Harvard said the class had changed his or her life.
What is it about the class that everyone loves so much?
"Everyone has this fundamental need to be happy," said Positive Psych student Robert Lord. "We need this in our lives. And it's not a Harvard thing. It's not a Cambridge thing. It's a human thing."
"Many of the things that I teach are common sensical," observes Ben-Shahar, "but unfortunately, common sense is not that common.
"So, the topics we cover are gratitude, goal setting, relationships, self-esteem, love, the mind-body connection … everything that will make you happier."
Ben-Shahar wants his goal-oriented students to learn that happiness is the ultimate currency, not money or success.
"One of the things that the course teaches you to do is to focus on the journey," says Harvard Positive Psych student Olivia Shabb. "It's not really about the material results of what you're going to get, but really enjoying every step of the process and appreciating all of the little things that go into the making of your life."
Do their parents think they're crazy for taking a class like that? Aren't they supposed to be taking something more Harvard-like?
"For me it's an extra class on top of my normal load," responded John Voith. "But I don't think anyone thinks I'm crazy for taking it."
