Work becomes powerful when it survives the disappearance of novelty.

Novelty carries the early stage and then leaves, and whatever remains after that is the actual project. Work that only functions while it is new is fragile, since newness is guaranteed to expire. Durability comes from something else, usually structure, obligation, or genuine interest in the material.

Ask what would keep you working on this once it is no longer interesting. If the honest answer is nothing, build that in now, before the novelty runs out.
