Credibility ain't really nothin' at all...
The key is not only to learn the formula for what builds credibility, but also for then using that to go build something real that will make the world remarkably greater. To actually deliver as opposed to creating the right signals without the intent of authenticity or commitment or even skill. I know how to make myself sound important enough to be heard, but who cares if at the end of the day what comes out of my mouth is mundane, recycled to the point of garbage or god forbid makes the room that much dumber?
It is your duty to be at your best, if not for you then for the world that you've convinced should listen.
