Wherefore art thou motivation?

I recently got a promotion, of sorts.  A promotion that comes with no pay raise but more hours.

I think I've lost my mojo for school.  I was so excited for it to begin but now that it has I'm so very tired.

I dropped one of my classes today and am now down to 12 hours. My online psychology class just wasn't happening.  I nailed a discussion question and didn't get full credit because I didn't "interact" with my classmates.  Then, today, I took my first test and got a 70.  A "70".  I don't make 70s, people.  The 14 pages of notes I took over the PPs and chapter readings did not help me because I was asked questions like:

You have a friend who works for a fast food chain and is dreading completing his performance appraisals.  What can you say to encourage him to complete them?

A. "No one pays attention to performance appraisals anyway!"
B. "Performance appraisals are an essential part of business and help develop effective training techniques."
C. "Performance appraisals help weed out employees that should be fired!"
D. "Just do your job and complete your performance appraisals!"

I selected "B" and got it wrong.  Less than half of the material I'd read over was on this test and those embedded quizzes that I scored 100s on weren't on there either.  So, I vented to Dwayne, dropped the class, and put my book up for sale on Amazon.  Over it. I'm too old for this kind of class.  I am also too stressed about classes that I need to proceed to mess around and try and scramble to make up for a 70 all semester.

I'm in study hall working, or blogging, with people who aren't motivated to do their work either.  So, as they avoid doing theirs- I'll avoid doing mine.
