Many of us believe that hard work and persistence are the key to achieving our goals. But is that true when it comes to the pursuit of happiness? This week, we kick off a month-long series we're calling Happiness 2.0. We talk with psychologist Iris Mauss, who explains why happiness can seem more elusive the harder we chase it, and what we can do instead to build a lasting sense of contentment. Did you catch our two-part series on the science of influence? You can find part 1 here.  And if you enjoy the show and would like to help us make more episodes of Hidden Brain, please consider supporting our work. Thanks!
