Don't solicit feedback on your product, idea or your business just for validation purposes. You want to tell the people who can help move your idea forward, but if you're just looking to your friend, co-worker, husband or wife for validation, be careful. It can stop a lot of multimillion-dollar ideas in their tracks in the beginning.
