In this BBC Maestro course, Mo Gawdat, former Chief Business Officer at Google X, explains how to predictably achieve happiness through understanding the 'happiness equation' and managing your thoughts.

Do you ever feel like you're working fruitlessly toward a set of conditions society has told you are necessary for happiness?

Mo Gawdat is the former Chief Business Officer at Google X and a self-proclaimed math nerd. Finding himself unhappy despite his success and wealth, he began developing an equation for happiness.

Happiness, Gawdat found, did not come from adding things to his life but from the absence of unhappiness, a default state we can all return to by eliminating the things that make us unhappy.

In his BBC Maestro course, Happiness, Gawdat shares his happiness equation, helps you to understand what happiness looks like for you, and gives tips for managing the expectations that often rob us of happiness.
