TED：快乐可以合成？

Some things are better than others. We should have preferences that lead us into one future over another. But when those preferences drive us too hard and too fast, because we have overrated the difference between these features. We are at risk.  

生活中确实存在某些事物比别的更有价值。我们确实应该追求价值更高的东西。但假如我们过分看重不同选择之间的差异，因而拼命地追求我们想要的东西时，我们就可能面临危险。
