Pip really does not make any plans for himself. Magwitch makes plans for Pip to become a gentleman. He arranges for him to go to London and stay with Herbert Pocket and take lessons from Matthew Pocket, his tutor.
When Jaggers arrives, he tells Pip that he has a secret benefactor who has given him “great expectations” and he is going to come into property.
Further, that it is the desire of the present possessor of that property, that he be immediately removed from his present sphere of life and from this place, and be brought up as a gentleman… (ch 18, p. 97)
From this point on, Pip simply goes with the flow. He has an idea that Miss Havisham is raising him up so that he is less common and can marry Estella, but she never confirms it and in fact his expectations have nothing to do with Estella.
The book tells us about the main protagonist, Pip, known as a bildungsroman, presenting the growth and change in character of a single person. He is the one who changes the actions and the whole plot of the story and is also the narrator himself who changes the reader's perceptions and thoughts about the book.
He has a plan to improve himself and get any possible social advancement whether is it moral or educational. He also wanted to take a hand in marriage with Estella to join the upper classes in the social monarchy as he hates being in the lower classes. He has a simple vision of being with the rich and the famous and live a grandeur life, to be less inferior in other people's mind. To do all these things, he has to become "less common" in the society, a rare gem in the jewels, becoming a pure gentleman. His first step of his plan keeps off to a flying start as some benefactor who didn't revealed himself offered him an good education to kick start his career, but he was shocked when the secret benefactor was that the wretched Magwitch, not the benevolent Miss Havisham was the secret benefactor to his successful career, shattering Pip's simplified version of the world's hierachy and makes him ponder over his actions and decisions that he did and the path that he himself chosen, and so he matures into a real man with real character, the steel within.
The first thing Pip does is aspire to be educated. He goes to Biddy to try to gain all her knowledge. Finally she says that she has taught him everything she knows. Then, Pip tries to act more gentlemanly, though he does not know how.
As far as I know, Pip did not have a long term plan for making himself less common, though as he becomes a gentleman through his benefactor, he keeps pleasing Estella in mind. He always feels inferior to her, and has a general desire to make himself her equal, by whatever way may come into his path.
Great Expectations tells the story of Pip, an orphaned boy from the lower classes who has always had visions of a grander life. When Pip is suddenly offered an education by an anonymous benefactor, this vision becomes a reality. Pip is able to maintain the lifestyle of an English gentleman, and he hopes his improved fortunes will gain the love of Estella, a girl he believes will only love him if he is a gentleman.
The novel makes a commentary on the rigid social class system of Victorian England but, more simply, it is also telling the story of a young man (Pip) and his efforts to understand what is truly important to him. When Pip discovers the identity of his mysterious benefactor, he is forced to confront some truths about himself and the life he has chosen.
