What holds many people back from attaining the success they want - whether it's winning an Olympic medal or a seat in the C-suite - isn’t a lack of effort or talent. It’s the fear of other people’s opinions. That’s according to Michael Gervais, a performance expert and founder of the consultancy Finding Mastery. He works with top athletes and executives around the world to help them overcome FOPO and improve their performance and well-being. Gervais is the author of the book The First Rule of Mastery: Stop Worrying about What People Think of You.
