If you want to use Great Expectations by Charles Dickens, one approach might be to focus on the true meaning of success. In Great Expectations, Pip grows up as a poor boy whose mysterious benefactor takes care of him and gives him every advantage throughout the years to be the gentleman he so desperately wants to be. Pip's values as he grows becomes somewhat superficial and elitist, which is ironic, because his mysterious benefactor, the one who is making it possible for him to live in the world of "gentlemen" is actually the convict that Pip befriended when he was a little boy.
When Pip realizes that Magwitch, the convict, is the one who has given him the gentleman's life, and that Magwitch is dying, he begins to return to his true self and his true values, and treats the old man with dignity and respect. In the end, it is not the money, education, and fine material objects that made Pip a true gentleman, but rather his return to who he was, to true values, and to a recognition and appreciation for what this convict had done for him. In many ways, the truest gentleman of the story is Magwitch himself, the one who Pip at one time likely would have looked down on.
