MENTAL MODELS TO HELP YOU MAKE THE BEST OUT OF LIFE: We live in a complex world. The diversity in people, institutions, natural forces and the rise of technology has created a world that is increasingly challenging to navigate and has made happiness more elusive than ever. A mental model explains how something works in the real world. This book's collection of mental models can help you excel in and integrate all five domains of life: Love, Health, Work, Parenting and Spirituality. The book is based on the premise that it is not enough to achieve success in one of these domains of life. The house of happiness stands on several pillars, and each needs to be strengthened if you want to achieve long-term happiness and well-being.
