reading a good book, listening to your favorite music, or spending time with close friends.

      Another secret to leading a happy life is to be active, and have hobbies where you forget your problems.

Many people experience this dancing, or playing a sport, such as skating or soccer.    3    

      Finally, many people find happiness in helping others. According to studies, people feel good when they

volunteer their time to help others.    4    You can help a friend with his or her lessons, go shopping to buy

food for your family members, or simply help out around the, house by washing the dishes.

A. If you want to feel happier, do something nice for something.

B. The first secret of happiness is to enjoy the simple things in life.

C. Most people want to be happy, but few know how to find happiness.
