The purpose of an elevator pitch is to describe a situation or solution so compelling that the person you're with wants to hear more even after the elevator ride is over.
I like to keep people around me like the guys I have on the road with me, three of them were childhood friends of mine when I was growing up in Scotland. They don't look at me any different than when we were in primary school. So it's good to keep people like that around you. I think if you surround yourself with good honest people, they will tell you what to hear when you need to hear it.
