This question is about identifying the main idea of a paragraph. The correct answer is C because the first paragraph describes the author's transformation from a proponent of 'having it all' to someone who is happy with a simpler life. Option A is incorrect because the passage does not focus on pride in achievements. Option B is wrong because the author's tone is not critical but reflective. Option D is incorrect because the challenges of being a writer are not the main topic of the paragraph.
