IMO, the hole metaphor is terrible. Mountain of trash feels more accurate. Problem is, after it's all cleaned up, there is no hole to fill. There's just nothing more to do, except whatever comes at you. That gets boring pretty quick in a relatively non-hostile environment. Playing Minecraft in peaceful mode never made me happy. Trying to figure out why that is is what I'm working on now. I think that's just creativity for it's own sake but, even though I find joy in other people's creativity, I find little point in doing it myself. Now that I'm typing this out, maybe something like "challenges" and "achievements" is what I should be "creating". Craft my own trash pile.
