Most people would rather be right than happy. Too bad.
For those people (which of course includes me, far more often than I would like), I recommend this book, which teaches ways to defuse stress and thrive with all of life's challenges.
Barry Neil Kaufman, therapist, author, motivational speaker, and co-founder of the Option Institute, observes that - despite disappointments, illnesses, and physical and emotional problems - we can all be happy. He shows us how to change our lives without pain (the only overlooked major point is that it does require focus and repetition to change how our brains work).
I read hundreds of books every year but, if I were forced to choose just one, this would probably be it. It created such a positive impact on the quality of my life! Only quibble - this is the book that should have been called "Happiness is a Choice" but Kaufman had already used this title for a previous book.
This is one of my top four books on happiness. The others are: "How to be Happy" by Kline, "The How of Happiness" by Lyubomirsky and (for its detailed action steps that work well with Lyubomirsky's book) "Emotional Toolkit". All provide good practical advice.
[Later note: "The Longevity Project" by Friedman and Martin is a groundbreaking 80-year overview on what is really directly linked to happiness and health.
I am also impressed with "The Healing Code by Lloyd - an amazing process for emotional clearing. There are hundreds of success stories, including physical healings, on Amazon.com.
