Keep the learning when you move to the next project.

Save the context with the result

A message that worked for one audience may not work for another. Record who saw it, what problem it addressed and what action they took. Without that context, a winning headline can become an unhelpful rule of thumb.

Separate the principle from the execution

The useful lesson may be that buyers responded to a simpler buying process. The exact words, image or channel may be less transferable. Identify the underlying idea before copying the execution into a different project.

Treat reuse as a new hypothesis

Bring the lesson into the next project as a question worth testing. Keep the first experiment small and define what would support the idea in this new setting. Reuse can shorten the path to a good question without removing the need for evidence.

Keep the library readable

Use short titles and plain language. Link each lesson to the experiment that produced it and mark what remains uncertain. A small collection of clear notes is easier to use than an exhaustive archive nobody wants to open.
