If you live in the United States, the law(法律) says you can’t have a full-time job until you are 16 years old. At 14 or 15, you can work part-time after school or on weekends, and during summer vacations you can work 40 hours each week. Does that mean if you are younger than 14, you can’t make your own money? Of course not! Kids who are between the ages of 10 and 13 can make money by doing lots of things.

Valerie, 11, often makes money by cleaning up other people’s yards. Lana , 13, makes money by knitting（织）sweaters for dogs and selling them to her neighbors, and Lisa said she had started taking art classes and showing her works to people. People have asked her draw pictures for them and they pay her for them. Jasmine, 12, writes articles for different magazines!

Making money is learning. By working to make your own money, you are learning the skills you need to succeed in life. These skills can include things like getting along with others, using technology(技术) and using your time. Some people think that asking for money is a lot easier than earning(挣) it. However, when you make your own money, you don’t have to depend on someone else. The five dollars that you earn will probably make you feel a lot better than the twenty dollars you ask for.
