In his million-copy bestseller, THE 80/20 PRINCIPLE, Richard Koch showed readers how to take advantage of the simple fact that 80% of your results come from 20% of your efforts. In 80/20 BELIEFS, he shows how just a few core beliefs - often unconscious yet profoundly influential - shape our lives, happiness and success. By identifying and examining the 'toxic' beliefs that cause unnecessary stress and shaping them into good beliefs that foster resilience and joy, we can enjoy a life of greater fulfilment.
