The central idea is that Tan didn't let her manager get to her, but instead she strived for what she wanted
Explanation:
I know this because in the passage it says "Tan was offended by what her manager said about her writing skills. Tan chose writing even though English was not her strongest skill." This is letting me know that even though Tan's manager doubted her, she didn't let it get to her. Tan was adequate about what she had wanted to do in life, and she stuck to it. Being successful takes an lot of practice, time, and of course hard work.
