Pink! Congratulations to you!
I know exactly what you mean, as I am about to finish my M.A. studies in a couple of weeks. This Friday I have my comprehensive exam, and I have been going over past research and trying to focus my thinking so I can express myself rationally and intelligently for the 3.5 hours of writing in the exam. But, i'm dreading it and actually procrastinating about taking notes, as I'm so damn tired!
Like you say, I too look on this as a time of valuable learning and self-discovery, but I will be so glad to get this study finished and behind me.
Congrats again!
Patty
