This is a strong essay! This draft has really a strong beginning, that scene of bird gaining power to actually fly is amazing alluding to your aspiration of obtaining pragmatic experience in NW.
But yes, I agree with the advices given above. After the beginning you might want directly enter your main theme of your life in NW, like
As I was reading Northwestern, the book I received in the mail, I remembered an old LG TV advertisement titled Live Borderless..
Then, " That's exactly what i want from Northwestern and what it can bring to me". things like that, maybe prettier~!
Also, you might then add some specific details of the programs and internships NW can offer you. Name them. It shows that you've done many works on it!
And after all, you're using the whole second paragraph talking about NW's activities. It's better to return to the flying-bird theme in the beginning. You might just mention it once or twice in the end, and make your draft more coherent and pact!
Those are just some personal suggestions! I'm new on this! Wish both os us good luck and thank you again for your advice on my draft!
