life in thesis land

I started a master's program 2 years and 11 months ago. It is a two year program; I still have not finished. I have loved all of my classes and field experiences; I cannot set deadlines for myself. My committee has been very understanding; I don't need understanding, I need strict deadlines with consequences. I thought that setting a deadline of finishing before I went to India would be enough. It wasn't. I thought that setting a deadline of finishing before I went to library school would be enough. It wasn't. Now, here I am, poised on the brink between being young and being a full-fledged adult, and I still can't do it. I cannot bring myself to the computer long enough to write a thesis I would be proud of. I've done all the research (not that I remember much of it anymore, but I wrote it all down somewhere). I've even started the writing (of course that was last summer, and I haven't done much since then). I don't like any of what I've written, and I'm trying to start over. However, I have a job lined up, a real job, that requires this degree. I start working in less than two months, and I still can't do it. Any thoughts?
