To help people learn how to flourish, Alphonsus Obayuwana, MD, PhD, CPC, has developed a five-minute tool that can assign a numerical happiness score to any individual—whether a peasant or a millionaire—using a universal unit of measure called Personal Happiness Index (PHI).
The scale was introduced in Dr. Obayuwana’s new self-help book, The Happiness Formula, which teaches people how to create a self-help routine for achieving and maintaining true happiness.

“Unlike other books about happiness, which are too often filled with dos and don’ts, wishful thinking, and empty aphorisms, The Happiness Formula breaks new ground,” said Dr. Obayuwana. “Despite its title, The Happiness Formula is much more than a mathematical equation for measuring happiness. It is a book about life, the relationship between human hope and happiness, one’s overall feeling of personal satisfaction and subjective well-being.”
