One hobby that many enjoy is writing. They may write poems in the margins of their school books or they may sit at home at night and weave tales on their computers. Some that write never show it to anyone, but for hobbies that make money, this is one that really can earn a living, or at least some extra cash for anyone that has some talent. Not everyone can be a writer, but most that can put together a decent article with proper grammar and spelling can find a way to sell it at some point by looking for writing opportunities on line or through local publications. You can start your own ad supported blog as well.
