I never pay attention to the corners, and I do just fine. And I daydream all the time. I'll just be sitting there photoreading something, and then my mind starts thinking of something else. Like what I'm going to do later on in the day. Or I'll start thinking about some fantasy novel I just read, and picture what the world would be like, with all those elves and hobbits, etc, etc, etc. You just really have to play with the system and see what works best for you.
