why does writing make me such a jerk?

Does this happen to you too? When I'm really working on writing an article, I become nearly insufferable. I become very distant and then argumentative when you can get through to me. I tend to begrudge anything that gets between me and writing.

I know. It's tiresome, cliche even, right? Some people may find this single-mindedness to be an admirable quality. But I don't. I am finding it increasingly unhealthy and certainly not positive. I've been thinking that if the my mental habits of scholarly writing lead to such bad behaviors and mental states, then my mental habits need to be rethought. I don't think, btw, that being intellectual necessitates such bad mental habits.

I just need to pursue a practice of mindful writing. Any suggestions?
