While some people rise to a challenge and function better in difficult situations, others fall apart. The difference between too much pressure and too little can result in either debilitating stress or demotivation. The right level of challenge, however, can help people flourish. This level varies hugely between individuals and situations but when reached it is what Robertson refers to as the 'sweet spot'. This spot can be changed, and in this book, based on his own research and clinical observations, Robertson reveals how we can use the sweet spot to control stress and boost performance.
