I Am Worried

I feel like a real loser at my job. I'm a reporter and I send my editor my drafts and he keeps sending them back to me asking for revisions and what [i]he[/i] prefers to have in the article instead of the angle I'm getting at. I get it, it's his job but he always rewrites my work anyways no matter what I send him. Last night, he told me how frustrated he was that he spent hours revising my article. And for another story I did, he didn't like the pictures I took. He just makes me feel like I'm incompetent for the job and I'm scared that he'll fire me the more I disappoint him. I really need this job so that I can get published experience.
