We have a natural desire to connect, which is just as important as our need for food or air. One study showed that the difference in happiness for people who were isolated versus those connected with others was equivalent to the difference of earning an extra one hundred thousand dollars per year. Although connecting with others brings great happiness, many people find it difficult. Aside from the importance of social skills, this book illustrates the secret of how our brains are wired to connect from the perspective of human nature. It seeks to help us build better social relationships and discover hidden social strengths.
