For many people, happiness seems to be something elusive. Some wish to find happiness but have no idea how. ‘Happier: Learn the Secrets to Daily Joy and Lasting Fulfillment' is the literary version of Harvard’s most popular course on happiness. The book explains the underlying reasons why most people are unhappy and informs us that happiness is the measurement of a successful life. True happiness is “the overall experience of pleasure and meaning.” Increasing the sense of happiness can help us get rid of existential anxiety, release individual potential, and improve our quality of life.
