Probably because for you just the act of completing something is _fun_. Personally I'm reading or playing a video game because of the entertainment it provides. If it's not interesting or doesn't hold my attention, it's not worth slogging through it. Life's too short. That's one big plus of digital entertainment: I can refund what I don't like in a single click, I don't feel like I _have_ to finish it nor I have to justify my reasons to anybody. Though I have to admit I've bought for the second time some video games or books I had previously refunded, because I finally understood what's the correct mindset to have to enjoy them fully.
