My thesis topic was basically handed to me by my undergrad boss. At the time, I figured, "Hey! This is great! I have a huge head start!" However, I never had much interest in the topic to begin with, and now I'm in the process of writing the stupid thing so I can graduate in May. I'm miserable and unmotivated, and it's way too late now to do anything but get it done.
Not looking for any advice. Just commiseration. Anybody else?
