I've been thinking about trying to become a freelance writer a lot lately. I want to be a novelist in the future and I decided the freelancing can really only help at the moment. However, I'm not really sure how to go about becoming one, and if it really would be worth it in the long run. Where should I start looking? How do I know that the prospective employer won't not hire me but steal my ideas? Is there a way to protect against that?
