Our inner voice is a powerful compass that helps us navigate the world. At its worst it can seem like a demoralising critic, hellbent on sabotaging our potential; but if it is positively harnessed, it will become an inspiring coach and lifelong guide. In this book, psychology professor Ethan Kross brings more than 20 years of research to demystify the voice inside our head. Weaving cutting-edge science with compelling true stories, he shares powerful but simple tools to make your brain's musings work for you.
