Definitely keep writing, but start promoting, too. You could have the greatest blog in the world, but if no one knows it's there, you'll never see the results you want!
Look into some guest blog posting. There are alot of blogs that take guest posts. That will give you a great chance to get your link out in front of a very targeted group of people. And, if people like what they see, they could very well wind up as loyal readers of your blog!
Good luck! And remember, seeing success takes time.
