I am a confirmed book addict. I go to the library, and come out with my backpack bulging and my arms full of books. I need variety. I'm very ADD, and love switching from book to book. I usually have three or four books going at the same time.
I'm not terrible picky about the subject of my books---right now I've gotten into a homeschooling jag. If I ever have kids, I want to homeschool them. I've worked in both public and private schools, and nothing can beat the individual attention and flexibility that homeschooling offers.
I also have travelogues, books on Attention Deficit Disorder, and Uncle Tom's Cabin. I have a couple of real light reads, just to balance it out. What are you reading right now?
