This flowchart below was adopted from the book The Power of Habit by Charles Duhigg. In his book he explains why habits exist and how they can be changed. With penetrating intelligence and an ability to distill vast amounts of information into engrossing narratives, Duhigg brings to life a whole new understanding of human nature and its potential for transformation.
Along the way we learn why some people struggle to change, despite years of trying, while others seem to remake themselves overnight. The key to exercising regularly, losing weight, raising exceptional children, becoming more productive, building revolutionary companies and social movements, and achieving success is understanding how habits work.
