I've never been afraid to share bad ideas because the best way to get to a good one is to go through the bad ones. Sometimes my bad ideas will spark a good idea from somebody else or sometimes it even turns out that my bad idea isn't bad at all and people like it and we end up adopting it.

Either way, not being afraid to look dumb keeps the juices flowing. And keeps the conversation going. Or sometimes it starts the conversation that nobody else is willing to start.
