Professor Schwartz assembles his argument from a variety of fields of modern psychology that study how happiness is affected by success or failure of goal achievement. As Americans, we assume that more choice means better options and greater satisfaction. But beware of excessive choice: choice overload can make you question the decisions you make before you even make them, it can set you up for unrealistically high expectations, and it can make you blame yourself for any and all failures. In the long run, this can lead to decision-making paralysis. And in a culture that tells us that there is no excuse for falling short of perfection when your options are limitless, too much choice can lead to clinical depression.
"Autonomy and Freedom of choice are critical to our well being, and choice is critical to freedom and autonomy. Nonetheless, though modern Americans have more choice than any group of people ever has before, and thus, presumably, more freedom and autonomy, we don't seem to be benefiting from it psychologically." —quoted from Ch.5, "The Paradox of Choice", 2004
