Happiness is important for everyone. Most people want to be happy but few know how to find happiness. Money and success don't 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.
