Your idea sounds half-baked in your head because it hasn’t been said out loud yet. Pitch it and let it cook.

Thoughts do not finish in private. An idea stays vague until it has been said to another person, because speaking forces the gaps into the open where they can be filled. What feels half-formed is often just unspoken, and keeping it in your head is precisely what stops it from developing.

Say the rough version out loud to someone this week, with the caveat that it is rough. Let their questions do the shaping. You are not asking for approval, you are using another brain to finish the thought.
