Any literature references from the following: novels, short stories, plays, movies, or poetries. If possible, please give a brief summary.
I would offer Firzgerald's "The Great Gatsby" as a good choice. Each character makes choices. Daisy chooses to marry Tom instead of waiting for the "poor" Jay Gatsby. Gatsby chooses not to get over Daisy, so he makes his way, presumably less than legally, to becoming a rich man so that he might win her back. Tom chooses to cheat on Daisy with Myrtle. Daisy chooses to cheat on Tom with Gatsby. Myrtle chooses to run from her husband when he discovers that something is going wrong. She chooses to run into the street. Gatsby, after Daisy has fought with Tom over his affair and her affair, chooses to let Daisy drive a car that he chose to let Tom drive earlier. Because of this (and lots of other choices) Daisy killsy Myrtle. George recognizes the car. He goes after Tom, thinking Tom killed her. Tom tells him that it was Gatsby's car. George kills Gatsby and himself. Daisy returns to Tom. Three people are dead, teo affairs are ended, and everything returns to "normal" all because of choices; but what really makes this interesting is that Nick, the narrator, sums it all up when he realizes his disgust with the fact that rivch people make careless choices with no regard to the consequences of their actions/ So, if I were to choose a work of fiction about choices, I really think that this is one of the best!
I would also offer George's decision to kill Lennie in John Steinbeck's classic novella, Of Mice and Men. George and Lennie share a very special and close bond of friendship. Although Lennie is "slow," (his exact mental affliction is never directly named), he and George share their vision of the American Dream and an "us-against-the-world" outlook on life.
In these quotes from Chapter 1, George and Lennie talk about their dream:
Guys like us, that work on ranches, are the loneliest guys in the world. They got no family. They don't belong no place....With us it ain't like that. We got a future. We got somebody to talk to that gives a damn about us."
"An' why? Because...because I got you to look after me, and you got me to look after you, and that's why."
"'Well,' said George, 'we'll have a big vegetable patch and a rabbit hutch and chickens. And when it rains in the winter, we'll just say the hell with goin' to work, and we'll build up a fire in the stove and set around it an' listen to the rain comin' down on the roof...'"
However, when Lennie panics and accidentally kills Curley's wife, George has to do the hardest thing imaginable. He shoots Lennie in order to have him die humanely. If he had let Curley and the mob get him, Lennie would have been tortured before he met a gruesome death. Near the water, where the two had agreed to meet should anything "bad happen," George tells Lennie to turn around. He asks him to recite their dream about their ranch and the rabbits. As Lennie happily does so, George shoots his friend in the back of the head. It is an act of love, and it saves Lennie from a terrible, terrible fate but it definitely changes George forever. He is now alone in the world and has no one to share his dream with.
Wow, ... I actually have a harder time figuring out a piece of literature that doesn't indicate how a decision or action changes someone's life! However, since you are asking for one that does, I will give you the absolute best example I can think of: To Kill a Mockingbird by Harper Lee.
The decision of Atticus Finch (a white lawyer from Maycomb) to defend Tom Robinson (a black man accused of assaulting a white woman) changed Atticus' life, turned his children's lives upside down, and in fact changed the lives of the entire community of Maycomb. The Finch family is subjected to the worst of violence because of their actions against the racism of the South. The children, Jem and Scout, struggle to understand and eventually learn the importance of their father's decision.
I'll also give you a more modern example: Going Rogue. Within the confines of this non-fictional autobiography, Sarah Palin's realization and pro-life decision as a result of her unborn child Trig being diagnosed with downs syndrome, changed her entire life and the life of her family. To Sarah, this "decision" wasn't a decision at all, there was no question in her mind. Sarah Palin would never consider abortion. However, this experience did give her empathy towards women who have faced the same situation, while proving the awesomeness of God's blessing in giving her such a very special and loving child.
In the short story, "The Necklace," by Maupassant, Mme Loisel makes a decision that forever changes her life. She decides to borrow a necklace for the ball. After the ball, she loses the necklace. In a panic, she searches for the necklace but cannot find it. She then borrows money to replace it.
Mme Loisel has to work ten long years to repay the loan. She suffers greatly from the hard work. However, she learns a valuable lesson about life after meeting Mme Forrester in the park. She tells Mme Forrester the whole story about losing the necklace and borrowing money to replace it.
Mme Forrester then tells Mme Loisel that the necklace wasn't real. It was an imitation.
In the end, Mme Loisel has learned to be content with life as she knows it. She no longers "suffers incessantly" because she does not have the finer things in life.
