A defeated prop onchain usually doesn't indicate failure, but a chance to revise and go again. 

To the proposer it can feel that way however.

100% I’m trying to be better about building that muscle bc it definitely feels like failure on a couple of fronts

Agree, defeat just means the mechanism needs refinement.

depends on critiques. if thoughtful, then yes, totally revise. but if reactionary, then don't spend any more time.

Losing a vote doesn’t mean the idea’s dead. Just means it wasn’t ready yet.
