I read something recently that said having a PhD is not a testament to how smart you are. It is merely a sign of your ability to survive.

I think that's true. Technically, I'm not even at the PhD phase of my graduate career. But, I'm hanging on by a thread to finish my MA thesis...I'm sure by the time I'm writing a dissertation, I'll be hanging on by a very thin, quickly unraveling thread. I thought I would finish my thesis Saturday. Then I said, "I'll finish Sunday." Then, it was yesterday. And today, I really am going to finish it. For real. I have to give the draft to my advisor asap. So, today it is. I'll post something tomorrow.
