Weighing probabilities of happiness

Victor's job—at its core—is to change the world. But he feels like he's plateaued within his large humanitarian and development organization, and is now on the verge of jumping ship. On this episode of How To!, Annie Duke, author of Quit: The Power Of Knowing When to Walk Away, helps Victor decide if he should recommit to his current job or move on to something else. She explains the cognitive biases that prevent us from quitting and reveals why most of us quit things far too late.
