Maps
Maps are a great metaphor for ... well, no spoilers.
I remember one of my college professors paraphrasing a quote that I think was also misattributed. He said (and I, myself, must paraphrase...) "The most accurate map would be one that you could unfold, step inside, and walk along the map to where you want to go. All the trees, all the bugs, are exactly where they are. When you get to your destination you step outside the map and fold it back up, and you're where you want to be."
My professor said the quote originally came from Alexandre Dumas; But given I have to Google a paraphrasing of a paraphrasing, it's been hard to find the original quote.
Closest I've seen is comedian Steven Write's joke: “I have a map of the United States... Actual size. It says, 'Scale: 1 mile = 1 mile.' I spent last summer folding it. I hardly ever unroll it. People ask me where I live, and I say, 'E6.”
