I have yet to pitch to investors. That said, when I am pitching an idea or concept to others I always try to know what my end goal is, get my verbal or visuals all figured out so my conveying of ideas and such is as smooth as can be.
I want people who are willing to explore ideas and random concepts, but who also have faith in trying and failing. I am not looking for someone who is insincere in their interest or support nearly because of financial opportunity.
