This question is about "The work you do, the person you are".
Answer:
it shows that "erosion" has magnified it, rather than diminishing it.
Explanation:
As was said in the question above, the word "erode" has a meaning of deterioration, wear and tear. However, in the article mentioned above, Morison refers to this word as something that made it great. That's because she uses the word "erode" to show how her work was wearing her out and it took a lot of effort to do it, but she says that this wear made her bigger, because her salary gave her freedom and a good position within the family.
