If it's one thing that Stanford has made me realize, it's my utter lack of prioritization ability.  It was fine in high school when there wasn't too much to do, but it's been a problem since.  Trying to juggle everything and give each task equal priority = disaster.  I've definitely learned to let go of more things senior quarter and let things be.  First thing to go:  econ sections.  2nd thing to go:  exercise (my dad would be so disappointed).  I'm not sure if I'm prioritizing optimally, but things always manage to work out.  Relax and breathe....
