People who have several close friends often live happier and healthier lives.Another secret to living a happy life is to be active, and have hobbies where you forget your problems and time. Many people experience dancing, or playing a sport, such as swimming. You can forget about your problems, and only think about the activity.Finally, many people find happiness in helping others. Studies show that people feel good when they spend their time helping others. If you want to feel happier, do good things for someone.
