I must admit that I don't read fiction at all anymore and outside the occasional technical manual and frequent journal article/newspaper entry/online column I rarely read anything. Actually, I read quite a lot but the words are usually found on a screen. Reading on paper is fast becoming antique ;)
I have a tendency to stick to the self actualization, self improvement genre in relation to book reading. Unfortunately, like most people it seems that I start reading these titles but almost never finish. Maybe you can save yourself a buck or two by avoiding the these commonly started but seldomly completed titles on Amazon.
