Reading lulls..

I've been having troubles getting my butt to sit down and read lately. Which is odd, since I've loved reading since I could read See Spot Run on a page. I've always enjoyed curling up with a good book and getting lost in some adventures. However, it seems like more and more lately, even when I WANT TO READ and have books that I WANT to read, I still put it off. I got a TON of books for Christmas and I have not even read half of them. I have two books out from the library that I know I want to read and will enjoy, but have not started. I am so not going to make my reading goals for this year and it is making me angry. I should be enjoying the time I have now to read since I know there will be a lot of time in the future that I won't have all this time to read.

Why can't I just pick up a book?
