I believe that the first 19 chapters can be somewhat divided into 4 different situations that all come to be a significant part of Pip's identity. The first being the early years of Pip living with his sister and Joe, he values his education by wanting to develop his reading and writing skills yet he is still heavily impact by Mrs. Joe and Pumblechook's hope that Miss. Havisham will bring Pip fortune. As soon he visits Miss. Havisham there is a huge in what he values and now hopes that she will make him a gentleman. It is evident what is truly important to him when he finds out that Miss. Havisham has made him Joe's apprentice. He is dissappointed because he wants to move up the social ladder and no longer wants to be tied down by his home, sister, and Joe. Chapter 18 marks the turning point when he finds out he will be moving to London to become a gentleman. He acts ungrateful and snobbish towards the people who love him most because he is now "better" than them.
Social class is also brought into the picture by the contrasting characters of Biddy and Estella. Biddy is pure and good and is content with her station in life while Estella is cruel towards Pip and at the other end of the social spectrum as Biddy.
