Partially Examined Life considers why happiness so often presents itself as a problem. HERE.
On a related note, my First Year Writing Seminar, a first year writing seminar developed for first semester college freshmen, is going wonderfully. What a great, great bunch of kids this year. All doing the readings, all have plenty to say, all intelligent and polite. Wow. Blown away by this bunch. The seminar is called "What is the Good Life?" Basically faculty pick whatever topic they'd like to teach and then follow the basic outlines of a writing course with that content serving as the main center of reading and discussion. We are using Plato's Republic, Aristotle's Nicomachean Ethics, Epicurus' The Art of Happiness, Seneca, Montaigne, Schopenhauer, and Nietzsche.
Great class, fun to teach.
