Have you ever noticed that in childhood the feeling of happiness was much sharper? What secret have we forgotten as adults? Or more precisely: what did we not know in childhood, but know now - and this knowledge harms our happiness? Imagine a scale. At its extreme right point there is happiness, at its extreme left there is deep dissatisfaction with life. Raj Raghunathan, Ph.D. and professor at the University of Texas School of Business, believes that everyone can consciously move along this scale towards well-being. To do this, it is necessary to eradicate the “7 deadly sins against happiness” and improve the 7 habits of happy people, which the author describes in this book. The book is also published under the title “If you are so smart, why are you unhappy. A scientific approach to happiness."
