Crap.

On an independent study last quarter, the professor was unable to give me feedback during the quarter and now, after grading my final project, has given me the choice of

1) take a B now
2) make changes (estimated at 15-20 hours of work) to receive an A

Honestly, I don't have the 15-20 hours to put in this quarter.  In fact, cost benefit analysis tells me clearly to take the B and to continue bailing out (ladling water out) rather than take on more water on an already sinking ship.  I am going to sleep on it before responding, but I already know I will be making the changes.    There is something wrong with my brain.  This is why I wish I knew more about psychology, so I could understand why I make irrational choices.
