Writers often stagnate in the "finishing" phase; they have done good work, but they just can't bring it to completion. In such times, it's wise to remember:
I have several friends that are incredibly talented. They will start on projects but rarely follow through. They get bored or distracted or discouraged that it's not "perfect" and give up. Following through and finishing things is one of the most important things you can learn.
One of my favorite quotes is "Done is better than perfect." That doesn't mean making crap – I believe you should always strive for the highest quality you can – but you have to finish. I think a lot of my friends in this situation don't realize how in-demand their skills are. I think if you follow through on projects and just put the tiniest little effort into promoting yourself and have the tiniest bit of self-confidence, you can get the job you want.
