What is happiness? Happiness is the feeling when you feel so satisfied that you can go to sleep with a big smile on your face. That’s my definition of happiness. There are many things that can make a person happy, and every person has his or her own definition of happiness. My happiness depends on others. What truly makes me happy is helping others. Give clothes, food, money to poor people. To solve problems of others. When they become happy than I become happy. God made us to help each other. My happiness is in all these things.
