One step up, two steps back

I am having one of those blah days. Every time I feel I have a good day that is productive, I have another day where I don't do anything at all and I feel guilty. It is a catholic thing, I am sure. I wish I could complete all of my goals, so when I look back I don't have anything to feel bad about because I am ahead of the game. Motivation for my is at an all time low right now. Might be this cold weather, S.A.D. or the winter blues. You know what I mean?
