Where does all the time go?

My marathon is now just over one month away, and I am starting to doubt I will be fully ready.  The last few weeks have been, to put it simply, crappy on the training front.  Work and life seem to creep in and make getting the required training in hard.  It is easy to still find the time for my shorter runs (anything under 6 miles) but it is hard finding the time for the longer training runs and the really long run every week.  Any thoughts of a great first time in my first marathon are gone, now I am buckling down with the simple goal of completing and not dying!
