I had my first committee meeting in a long while on Friday with all the committee members who are in town this semester. To my very great astonishment, both had read the chapter I'd submitted and gave me back marked up copies - and I'd only given them the work a day and a half earlier! The meeting was generally quite positive, and reassured me about what I'd turned in. I felt much better about the material after the meeting than I had before it. There's a fairly good chance that I won't be able to submit until fall, but aiming for then is feasible, and I'd rather at least attempt to be realistic about the deadline I'm aiming for. There almost certainly won't be any funding for me next year, but if it's only a few months, that'll be okay.
So... this summer, I'll do my best to finish my dissertation.
