Most young kids don't have real jobs. But you can still make money. Ask your neighbors (邻居). You can also talk to your parents. They could give you some money if you help with the housework in your home. And you can put your money in a bank. Banks keep your money safe.
You work really hard to make money and may want to spend it. Before you buy something, ask yourself if you need it or want it and if you have enough money for it. Set goals (目标) for yourself. Maybe you want to buy a toy. That's a short-term goal. Or maybe you want to buy a car one day. That's a long-term goal. Make a plan for how much you will spend. Keep to your plan. And remember your goals.
You can also use your money to help others. Think about what is important to you. Do you like animals Donate (捐赠) your money to an animal shelter (收容所). Even a little help can make a big difference.
Remember: save, spend and share. Being smart with money is a good habit. Your future self will thank you!
