A freelance writer or novelist can always work from home. If you have a love of writing, you might want to try this out. Start by writing for small-time magazines or papers to build up your career. It's really important to network in this field because it's much easier to get your piece into an editorial publication if you know the editor. You can always opt for journalism school as a way of getting into the industry.
If you want to write the next great American novel, you can either start on your own or wait for National Novel Writing Month in November to write alongside thousands. If agents aren't biting, you may want to publish your book online as an ebook.
Becoming a blogger is also a possible career path, but a tough one as well. It takes a lot of time and dedication to build up a blog, so you definitely need a lot of patience and determination. Pick a topic that you're really passionate about and start filling it with content every day. Reach out to blogs to partner up with, offer to guest post for people, and interact with fellow bloggers on social networks such as Twitter, Pinterest, and Facebook.
