Make the idea visible before you try to improve it
When an idea is still only a sentence, it’s easy to argue about what it might become. A rough version gives you something real to react to.
Try making a few deliberately different sketches, outlines, or mockups before choosing one. Then ask: which version carries the feeling or meaning I wanted? Refine that one—not the one that merely looks most finished.
For example, if you’re imagining a calmer onboarding experience, a hypothetical first step could be three rough screen layouts: one quiet, one playful, one extremely minimal. Seeing them side by side can make the choice clearer than another round of abstract discussion.
The rough draft isn’t the result. It’s a way to find out what the idea is asking to become.
