Please read the following passage and answer the question: What's the driving force in the unfolding of the story? This text is a narrative story about how the author builds a successful career out of a simple idea. It is written in a first-person point of view with the events arranged in a chronological order. Conflict is the driving force in the unfolding of the story, such as his mother’s disapproval of his decision to change his career and his bosses’ failure to see the huge potentials of coffee bars. From all these, the reader can recognize the high pressure the author felt to make a daring decision and stick to his vision. Rhetorically, three figures of speech are applied to add some touches to the language, such as metonymy found in “Why was Seattle so taken with this coffee maker”, metaphor found in “My mind started churning” and parallel structure “It’s seizing the day and accepting responsibility for your future. It’s seeing what other people don’t see and pursuing that vision.”
