Can prove counterproductive:
Groundbreaking work by Iris Mauss has recently supported the counterintuitive idea that striving for happiness may actually cause more harm than good. In fact, at times, the more people pursue happiness the less they seem able to obtain it. Mauss shows that the more people strive for happiness, the more likely they will be to set a high standard for happiness—then be disappointed when that standard is not met. This is especially true when people were in positive contexts, such as listening to an upbeat song or watching a positive film clip. It is as if the harder one tries to experience happiness, the more difficult it is to actually feel happy, even in otherwise pleasant situations.
And so modern research comes way back around to … Aristotle.
