100 Simple Secrets of Happy People by David Niven
David Niven, Ph.D is a psychologist and social scientist whose research emphasizes an interdisciplinary approach to problem solving.
He currently teaches at Florida Atlantic University.
His books are summaries of meta-studies of various facets of life.
The book is divided into 100 chapters.
Nearly all the titles are action oriented statements.
Each chapter has an introduction and a case study which explains the broad logic of the action being asked.
The chapter ends with a brief description of a scientific study which forms the basis of the title.
The best way to read this book is a chapter at a time, preferably in the morning, and just evaluating how to incorporate the action involved.
Let the thought marinate in your mind and sub-conscience; you'll figure out some appropriate change, if required.
