My Book Club Dilemma

I am now looking at the stack of unread books on my nightstand asking myself, why did I sign myself up for two book clubs if I can't seem to read the books? Last month I got lucky and one of the book clubs I belong to chose a book I read a few years ago, but aside from that, I have yet to read any of the assigned books, hence the growing stack of books next to my bed and on my dresser. Now I am questioning whether I am against assigned reading, which probably dates back to my school days and wondering, do I quit the book clubs or find a way to overcome my inability to read assigned material? How do I get over my book club dilemma? I mean, I really wanted to read "Eat, Pray, Love" when I saw it at Costco last year, but when it was assigned for both of my book clubs I never got past page 29. I enjoyed the 29 pages I read, but somehow, couldn't finish reading it..... Wait! Maybe this has nothing to do with assigned reading, but another problem. Maybe the issue is time? Maybe I don't have the time to read because I am too busy training for marathons, writing a novel and being a mother, which is the reason I joined the book clubs in the first place: to have a night off once in awhile. Now I just need to find a way to read the books.
