Hell is other people. They can upset us, depress us and infuriate us. Their bad moods can bring us down. And their achievements can make us feel like failures. But it doesn't have to be this way.   

Psychologist Ethan Kross says there are simple things we can do to make our daily interactions a source of fulfilment and joy. 

Ethan's the author of Shift: Managing Your Emotions So They Don't Manage You and founder of the Emotion and Self Control Lab at the University of Michigan
