Have you made money from doing work? Now you have a choice to make. What should you do with it?
It is okay to spend some of it. You earned it. But it is also important to save money. One way is to put some into a bank account. The bank will keep it safe until you need it.
Or make a piggy bank at home. Almost any container will work. You can also donate money. You can support a cause you believe in. The money will help those who need it. That is just good business.
