Day 19 building AffiSpark

Yesterday I wrote that some of the highest-leverage product work ships nothing.

Today I think the next lesson is this: if the insight stays in your head, the product has not learned it yet.

Clarity work is fragile. You can see something clearly for one afternoon and lose half of it a day later.

The only thing that seems to preserve it is writing down the distinction that got sharper.

Not “think more about onboarding.”

More like:

setup friction is not proof friction

paid entry is not blind entry

conversion weakness is not one problem

Those sentences look small, but they change copy, onboarding, metrics, and roadmap decisions.

My current rule: if today’s lesson cannot be written as a crisp distinction, it probably is not sharp enough yet.

Founders: what insight only started compounding after you finally wrote it down?
