In fact , happiness is always around you put your heart into it. When you are in trouble  at school, you r friends will help you; When you study hard  at your lessons, your parents are always taking good care of your life and your health; When you get success, your friends will say congratulations to you; When you do something wrong, people around you will help you to collect it; When you do something good to others, you will feel happy ,too. All these are happiness. If you notice a bit of them, you can see that happiness is always around you. All these can’t be bought  with money. It’s a feeling of your heart.
