The best I can think of is freelancing as a content writer. Over the years, it will not only bring you money but would also help you to have better communication skills and great command over language. Besides that with each new project you will get to learn in detail so many new things.

Babysit, pick berries, deliver newspapers, help others with their yard work, ad posting on internet, walk animals, help out around the store of someone you know…ask around. Don't forget to enjoy this last bit of work free time in your life though!

i agree with the first answer, if you are tallented enough then the web is great for freelancing. Otherwise just mowing lawns or dog walking etc is something you could try. Not sure what the age for working is where you are though...

baby sitting, sell your close, mow grass, walk dogs, yard sale, or maybe your mom or any other family member would pay you to clean or help them do something.
