9. Etsy Seller,
By the time kids are in their teens most of them have found their callings and hobbies and the artsy ones can actually make some bucks online. Online shops like Etsy is a boon to craft makers and you can always start simple and set up your online shop just with a few samples made. The investments are less and if you are serious about art, it can, in fact, be a step to a future business.
