Feedback on ideas that are in development often feels scary. Sometimes even scathing.
The thing is, when we have an idea-in-development, we are still in the process of figuring out whether we believe in ourselves. And in that stage we are on hyper-alert for evidence that confirms the idea is bad, stupid, etc. (And we often interpret this evidence to also mean we are bad).
In these moments, if we can remember that feedback gives us signals about what is important to the feedback giver, then we can start to see feedback for what it is: information that we can decide to act on or not. Half-baked ideas still have a ways to go, and you get to decide how they get shaped and who gets to shape them.
