Silly question about essays

[hopefulslp1]

Hi so I have somewhat of a silly question. I decided to quote one of my favorite books in my essay and I'm curious if I should cite it at the end of my essay. I properly cited it in the body of my text but do you think I should add a formal citation at the end of my personal statement? I know that's the right thing to do academically but I don't want to have a random extra page with just one citation on it. Please help!

For your personal statement, if you are using CSDCAS it is likely that you will not have the space to spare for this citation, I used a quote in mine and just said "quote" as said by whoever and it was fine.
