Why do I have six monitors? Because I don't have room for eight.

We fill every space we're given

There's something brilliantly honest about this joke. On the surface, it's funny because it's absurd—the answer doesn't explain the actual reason, it just escalates the problem. But what makes it stick is that it perfectly captures how we actually live with our tools and obsessions. We don't decide "I need exactly this much," we decide based on constraints, then immediately wish we had more space for the next thing. It's not really about monitors at all.

This shows up everywhere in modern life. Your kitchen drawer is full because you bought things that seemed useful. Your phone storage is maxed out because you keep everything. Your to-do list is impossibly long because you can always add one more item. We're not rational planners carefully measuring out what we need—we're optimizers working within limits, always sensing there's room for just a bit more if the rules would only allow it.

What's interesting is that Pratchett isn't mocking this. There's no moral judgment, just recognition. We're creatures of appetite and adaptation. We work with what fits, then we resent the boundaries. Understanding that about yourself—that this impulse is just part of how humans operate—might actually help you stop pretending you'll be satisfied once you "get everything organized" or "finally have enough."
