One product gets cleaner faster than five half-finished ideas.
Not because the other ideas are bad.
Because a product needs decisions. It needs edges. It needs the uncomfortable part where everything cannot stay equally possible.
When the work is spread across too many surfaces, every decision stays soft. When the work has one target, the tradeoffs start showing up.
That is useful.
This essay is the shell for that lesson. The full version should explain which product needed the focus, what got cut, and what became clearer.
