No matter, that is what I'm here for, to set you off on the right foot. Interpretation is an educational activity which aims to reveal meanings and relationships through the use of the original objects, by firsthand experience, and by illustrative media, rather than simply to communicate factual information. Interpretation must relate what is being described to something within the personality of experience of the audience, or else it will be sterile. Information, as such, is not interpretation. Interpretation is revelation based upon information.
Interpretation is an art, which combines many arts.
Interpretation's chief aim is provocation, not instruction and it strives to present a whole rather an a part. That is why you are here, to practice the art of interpretation. Just remember an interpreter has a sacred duty to strive for greatness. There are two kinds of greatness, you know. Remember that, and you will serve the National Park Service well.
