Charles Dickens wrote "Great Expectations" primarily to save his paper business that was losing money. It was written as a serial so two new chapters would come out each week. Dickens wrote as he went so he could capitalize on readers' reactions and please his audience. For a deeper answer I would say that Dickens wrote "Great Expectations" as a book that he could pour himself into. There are many aspects in the book that relate to his biography. For example, his own father was put into jail because of debt just like the prisoner. The book ended up being shorter than Dickens had planned making it much more concise that his other works and causing it to flow much quicker. The over all mood of the story is what defines the novel. You can tell that Dickens is familiar with the events that he is writing about because the mood connects so well with the storyline. He also cleanly depicts settings and happenings through his figurative language. It's much easier to paint a picture for your reader when you know personally all the sights, sounds, and smells that a specific place has. He also embeds a lot of symbols that connect with a class based society. Social status is a large part of the time period and everyone strives for wealth. Through Mrs. Havisham's garden, Dickens shows how wealth seems so grand, but is actually decaying and rotten.
