Scattered wits take a long time picking up; and often before I had got them well together, they would be dispersed in all directions by one stray thought, that perhaps after all Miss Havisham was going to make my fortune when my time was out.
– Charles Dickens
Great Expectations, Chapter 17. Pip is conflicted between being content with life at the forge and his aspirations to become a gentleman and win the attentions of Estella. He believes that Miss Havisham is the one who will help him advance his social status and become wealthy. But Pip is jumping to unrealistic conclusions and deceiving himself here. Other than help him become an apprentice and give him a guinea each year, Miss Havisham has given him no reason to believe she is going to make him his fortune.
