The author investigates a variety of conditions to see if they do or do not promote happiness. The focus of the book is psychological studies, making the ideas more scientifically authoritative. It's strong points are an entire chaper devoted to "Love and Marriage" and a chapter on "Flow in Work and Play." The book concludes with an epilogue listing the key points of the book in 2 pages. Three cheers for brevity!Anicius Boethius (480 to 524) wrote "The Consolation of Philosophy" long ago while he was awaiting his execution. Boethius covered all the key points in Myers' book long ago and was more eloquent. Myers' does not really give you a guide book for living a happy life. He says, "The essence of happiness is pausing to savor the gift of our present moments." There is so much more to living a happy, fulfilling life than that. I recommend "Achieve Lasting Happiness" by Robert Canright as a better guide for living a happy life.
