The larger lesson is that the brain is a neural tangle of near infinite possibility, which means that it spends a lot of time and energy choosing what not to notice. As a result, creativity is traded away for efficiency; we think in literal prose, not symbolist poetry. And this is why constraints are so important: It’s not until we encounter an unexpected hindrance – a challenge we can’t easily resolve – that the chains of cognition are loosened, giving us newfound access to the weird connections simmering in the unconscious
