Have you also run into the attention deficit effect of all these short forms of media? Overriding my brain's desire to put a book down after a couple pages is certainly not my favorite pastime.

Part of that might be your book choice.

I found that when trying to rekindle my reading habit, book choice had a big effect. Some books are like vegetables you know you should eat but really don't want to and other books are junk food. Empty calories that you love.

Pick from the latter pile at first and rebuild the muscle.
