Could not have said it better myself.

This is a hard time of year.  It is cold, there is lack of sunlight, it just is blah.  Hard to be motivated to do things we like sometimes, much less things we do not. .........(like math problems)

But, we cannot forget that the work done now will effect our future, and all too often in April I have students wondering, "how do I get my grade up?"  The answer is DO NOT LET IT SLIDE NOW.
As tempting as it is, stick with it, and know your vices.

Check out this student's answer to #4.  Nailed it!  

What are your vices? Diet Mountain Dew is tried and true, but this past week it has also been peanut butter and chocolate chip cookies.  Not together, but that doesn't sound horrible.  

Now I have to ask, Weird but delicious food combinations?  Jelly toast with a slice of cheese.  (Don't knock till you try it)
