Lack of Motivation

So, I hope that I'm not the only one out there who finds it hard to get motivated.  Between finishing school (by Thanksgiving), a messy house, a baby, errands, and many other things that make my weeks so busy, I often find myself taking time that could be spent being productive turning on the TV or browsing blogs.  Help!  I really need to get over this horrible laziness that seems to have consumed my life.  I had this problem to a certain extent before Kennedy arrived, but now, every time she is asleep I start relaxing.  I do this a little too much because every time I actually start to work she wakes up.  What do you do to juggle your lives and still find the time/motivation to do the things that need to be done?  I would really love some ideas.
