单选题Decoding the Happiness FormulaHappiness is not only found but also created. This is the message of celebrated psychiatrist Jonathan Hammond in his new book, The Happiness Formula, which unravels the secrets of leading a happy and contented life.According to Hammond, happy people are healthier, have better relationships with their families and friends, and are more productive at work. Although it is true that much of people's happiness is influenced by their genes and other factors such as income and socioeconomic status, happiness is also heavily influenced by the activities people do in their everyday lives. Based on this, Hammond studied how people find joy in life. He found out that those who are active and positive experience lasting contentment, compared with people who live more passively and have a more negative outlook on life.He said people can motivate themselves to be happy by engaging in sports and participating in activities that help them find meaning in life. Doing simple things, such as dancing, singing, smiling, or laughing out loud also stimulates positive energy. Hammond stressed that the key to long-lived happiness is making the decision to stay optimistic.Hammond, who is also a respected professor at Southcane University, has authored different books about personality enhancement and developmental psychology. The Happiness Formula was launched two weeks ago by Leehorn Publishing House and is currently number one on the Fortnightly Informant's best-seller list.
