Five Weeks In: The Moment of Truth

Today was my last weigh-in before my birthday.  The moment of truth to find out if I had succeeded in my (admittedly very aggressive) short-term goal of losing 10 pounds by my birthday, which is Monday.

I had a good/average loss this week, but missed my short term goal by 0.2 pounds.

Still.  A loss of 9.8 pounds in five weeks is nothing to sneeze at.

I'm contemplating my next short term goal.  My youngest daughter turns 1 in a month, and I'm 5 pounds away from being in the next "decade."  I am considering making that my goal, but 5 pounds is 4 weeks is a lot to ask from me.  I'm trying to weigh my emotional stability of being aggressive and seeing how close I can get against me setting goals and never really reaching them.

WWYD?  Be aggressive and probably miss?  (But maybe not by that much?)  Or be conservative and choose a different goal?
