Scientists and academics have spent entire careers investigating what makes people happy. But hidden in obscure scholarly journals and reports, their research is all too often inaccessible to ordinary people. At last, social scientist and psychologist David Niven, Ph.D., distills the scientific gobbledgygook of over a thousand of the most compelling and important studies on happiness into easy-to-digest nuggets of advice. Each of the hundred practices, attitudes and habits for happiness is illustrated with a clear example and illuminated by a straightforward explanation of the science behind it to show you how to transform a ho-hum existence into a full and happy life.
