Why do I do this to myself?

To do:

1) 3 page reflection/write-up thingy, due Monday.
2) 6 page term paper, due Wednesday.
3) 6 weeks worth of journal entries, due Friday.
4) Big-ass presentation, Dec 5.
5) Yet another paper, length forgotten, due Dec 7.
6) Fic for hp_holidaygen, due Dec 1.

Work completed: One third of the term paper.

I think I can safely say that my habit of putting things off has come back to royally kick my ass.
