One particular thematic statement that is brought out in King's work is that the individual pursuit of hope is one that knows no limitation. Andy's imprisonment does not deter him from believing in and pursuing hope and freedom. This individual quest is one that is not stopped by the various obstacles that are placed in front of him. It is one that he believes internally and one that he zealously pursues. At the same time, Red must battle through his own sense of fighting through obstacles that compel him to lose his own individual identity for that of the institution, of Shawshank. While Andy singularly pursues his individual claim, Red's is a bit more elusive and one that he embraces after some level of challenge and difficulty.
In the book The Shawshank Redemption Andy struggles to maintain his individualism in a prison community where the effort is made to strip away each person's individuality. Andy has an education and is very good at accounting. He uses his talents and skills to continue to be who he was before the prison sentence for a crime he did not commit came about.
Andy continues to learn and focus on the things he enjoys such as music. The Rita Hayworth picture is another expression of his individuality.
I believe I would look at how; Andy maintained his dignity and individuality was through his skills and continued self-education.
