Somehow reminds me of this interview with Philip Rosedale (https://www.youtube.com/watch?v=jg43s9yPsaI) where he basically suggests to share your idea (even in early stages) with people around you. Because you might end up with a lot of positive insights & ways to make your idea more solid.
Smart people tend to prefer to listen to themselves and trust their gut, works fine in some cases but not when you're early stage. I think listening is a VERY HARD skill to acquire but once you have it things will magically start to make more sense.
