Procrastination Station

It's amazing to me that I am able to rate my undesirable tasks in such a way that I finish a number of "white goldfish" (not whales) that I've been trotting about with, while never finishing the one I set out to complete.

For example, tonight I renewed a prescription online, photocopied my car title for my refinancing paperwork, and found cocktail recipes for my grandma's Christmas party next weekend.  I'm now considering whether I would rather write a test on Modernist American short stories or grade Lord of the Flies essay tests.  At school this evening, I worked on unit objectives rather than lesson planning; I made myself leave my planning materials at school so I would only have the tests to deal with, but now the interwebs are oh, so attractive, and there is still that test to write.

Where does it end?
