Whether it's anxiety about going to the doctor or boiling rage when we're stuck in traffic, our lives are filled with situations that send us spiralling. But as difficult as our emotions can be, they are also a superpower. Far from being 'good' or 'bad', emotions are information. When they're activated in the right way and at the right time, they function like an immune system, alerting us to our surroundings, telling us how to react to a situation, and helping us make the right choices. But how do we make our emotions work for us rather than against us? Acclaimed psychologist Dr Ethan Kross has devoted his career to answering this. In Shift, he offers up groundbreaking research and dispels common myths - for instance, that avoidance is always toxic or that we should always strive to live in the moment - and provides a new framework for shifting our emotions so they don't take over our lives. Filled with actionable advice, cutting-edge research, and riveting stories, Shift puts the power back into our hands, so we can control our emotions without them controlling us - and help others do the same.
