endlessly waffling over my to read pile

For some reason I've been just finding it harder and harder to pick what to read next, despite a growing book pile of things that looked promising when I saw a review or such. I never had any particular system, so I'm not sure why it's a hurdle now. I suspect it's that I'm reading more ebooks, so the unread piles is somehow both usually hidden yet overwhelming when I look at it?

It used to be that my electronic reading was mostly fanfic, where somehow this is less of a problem with the way that's published, but currently I'm less fandom engaged, and looking more to books, but it seems such an effort right now to decide what to start. Meh.

Maybe I should just use a random number generator or something.
