Answer:
I can't tell you the number of times I've racked my brain wondering, "How can I make some extra cash?!" Well, while there's no easy or best way to do it, there are several different options. When trying to decide how to make cash, ask yourself, "What am I good at and what do I like?" When people see that you are skilled and passionate about what you pursue, they are more likely to take interest.
A good way to make some dough is to go through your closet and see if there's anything you no longer wear or need. That Christmas sweater from Aunt Vicki? That can go to a place like Plato's Closet or a thrift store. Stores like these evaluate your goods and give you the cash upfront. Another popular option is to babysit. Adults are always looking for teens to put on their list, and a way you can earn even more money babysitting is to be certified in CPR.
Basically what it comes down to is deciding what is best for you. Make a list of hobbies and interests you have, and cross each item off until you're left with one or two options. Then you can explore those and decide where you want to go from there!
