Fifteen years after Raj Raghunathan completed his MBA, he checked in on his old classmates and noticed something strange: many of those who had achieved the highest levels of career success were among the most dissatisfied in life. No matter how successful they were at work, they were prone to be unhappy and out of shape. Why were so many of his smartest, brightest friends so unhappy? Raj set out to find an answer to this problem, and undertook extensive research, looking at the happiness of not just students and business people, but also of stay-at-home-parents, lawyers, and artists, among others. From his research he came upon a startling discovery: even the smartest and most successful people–despite their intellect, their drive and their knowledge–make all the same mistakes in life as their less smart, less-successful counterparts. In fact, many of the psychological traits that lead to success can foster habits that get in the way of being happy. In his book, Raj identifies the misconceptions that smart people have about their happiness, the elements of their personality that distract them the most from achieving it, and then clears a path to building the habits and attitudes that enhance happiness in both the short and the long-run.
