Most people treat fatigue as a signal to stop. But the medieval Jewish philosopher Levi ben Gershom — known as Gersonides — made a striking observation in his commentary on *Proverbs*: the soul's capacity for renewal depends not on absence of strain, but on what he called *chiddush*, a word meaning genuine novelty. He argued that the mind resists repetition at a biological level — that exposure to the same stimulus, however good, produces a kind of deadening. Behavioral scientists would later call this hedonic adaptation, but Gersonides framed it spiritually: monotony isn't rest, it's a slow erosion. The practical implication is uncomfortable. If Sunday feels flat despite doing 'the right things' — exercise, quiet time, healthy meals — it may not be that you need more recovery. It may be that nothing in your week has been genuinely new. Novelty isn't a luxury. For minds oriented around growth and purpose, it's oxygen.

In the last 48 hours, what have you encountered that you didn't already have a category for?
