My first sweater....why can't I finish it.

okay so I'm trying to knit my son's first sweater...I bought the yarn over a year ago and have come up with every excuse in the book. This is my progress as of Thanksgiving. I'm going to take some more pictures to show my progress since then...yes I have made progress but I've also started about 1/2 dozen other projects. I just seem to have a mental block. Not sure if its the idea of making a sweater or this particular sweater. Of course the way my son is growing he may grow out of it before I finish it. I was thinking if I posted these pictures it might push me to get working on it again.
