Start off by remembering that less is always more. Verbose presentations and lengthy explanations do not impress anyone. Make sure you inspire confidence by stating the facts and veering away from fiction. Avoid over-forecasting and be realistic. Reveal your big picture, but be reasonable and responsible. A quote that is relevant to this goes as follows; “Know what you know, know what you don’t know and find the people who know what you don’t know.” In short it means you don’t always have to be the smartest person in the room.
