There are two specific, yet lofty goals writers strive for every time they commit words to paper. That goal is to write in such a way as to draw their readers into the written word.
If this goal is in fictional writing the author wants the reader to become so absorbed in the story that they are both satisfied, yet sad to see the story end.
If this goal is in non-fiction the writer accomplishes the objective by relating details in a way that leaves the reader interested in the subject and with a desire to learn more.
