Running a freelancing writing business is so much more than writing. The 'business' part of it can get lost in the shuffle. Marketing, marketing, marketing. Look up some sample marketing plans online and write one for yourself.

Networking is important, too. Connect with other writers and editors on social media and interact with them professionally. Read and comment on their writing, retweet their posts, share their Facebook messages. Then pitch them in an e-mail. They will recognize your name as one who has engaged with their content.
