Please answer this is urgent! So in my L.A writing I have to explain the author's purpose and they tell me to note the following: structure, word-choice, etc. Does that mean I have to explain them in my analysis?

This is my explaination:

So based on that, we can clearly see that the author's intention is to inform us that in order to become something inordinate, we have to endure and surmount the pain that comes our way. After all, based on the text-structure he’s clearly describing the extreme situation he’s in, by using words such as, “survive,”“punishment,” and “Navy SEAL.” As a result this forms an image about the difficulty that he's tolerating for the sake of accomplishing his goal.
