We all have habits, but how do we form them? How may we change the habits we already have? Charles Duhigg in his book, The Power of Habit: Why We Do What We Do in Life and in Business, describes the habit loop, why habits are hard to break, and the best way to make progress with changing a habit. Filled with engaging stories of well-known corporations and interesting people, the reader will learn how either the people included in these stories were or were not successful in altering patterns that developed a certain habit loop. For a self-help book, I found this book engaging and informative.
