finish my M.A.

My dissertation is due in September. I met my supervisor today and as a result feel terribly behind schedule: I only have a vague idea of my argument and have to choose between two possible topics, both of which are equally feasible. EEK! How can I choose? Intuition? Just choose the thing that sounds cooler? I’ve tried about a million decision making techniques and still don’t know what I’m doing. Maybe I need to take a break and come back to this later? Blech.
