     Happiness is important to everyone. Most people want to be happy but few know how to find happiness. Money and success alone do not bring lasting

happiness. Happiness depends on ourselves. In other words, we make our

own happiness.

     Some people believe that if they are wealthy, they will be able to do

anything they want, which means happiness. On the other hand, some people believe that holding a high position in the government is happiness. In this

way, you have not only money, but also many other things which can’t be

bought by money. However, other people believe that having lots of money is not happiness, nor is holding a high position in the government. These people value(重视)their beliefs, or their intelligence, or their health. They think

these can make them happy.

     Here are a few ways to help you be happier.

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

often, we spend so much time thinking about the future, for example, getting into college or getting a good job, that we don’t enjoy the present. You

should enjoy life’s simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have close friends usually enjoy happier and healthier lives.

     The second secret of happiness is to be active. Many people go dancing or play sports. People can forget about their problems and only think about the

activity.

     Finally, many people find happiness in helping others. According to

studies, people feel good when they volunteer their time to do many

meaningful things for other people. If you want to feel happier, do something nice for someone. You can help a friend with his or her studies, go shopping

to get food for an old neighbor, or simply help around the house.
