    Happiness is for everyone. In fact, ①happiness is always around you if you put your heart into it. When

you are in trouble at school, your 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 congratulate

you; when you do something wrong, people around you will help you to correct it. And when you do

something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them,

you can find that happiness is always around you. ②Happiness is not the same as money, it's a feeling of

your heart. When you are poor, you can also be very happy, because you have something else that can't be

bought with money. When you meet with difficulties, you can say loudly you are very happy, because you

have more chances to challenge (挑战) yourself. So you cannot always say you are poor and you have bad

luck. ③If you take every chance you get, you can be a happy and-lucky person.
