Writing quotes, courtesy "Biloxi Blues"

Eugene Jerome: Why is that we come from the same background, but I can't understand you?

Arnold Epstein: You're a witness. You're always standing around watching what's happening, scribbling in your book what other people do. You have to get in the middle of it. You have to take sides. Make a contribution to the fight.

Eugene Jerome: What fight?

Arnold Epstein: Any fight. The one you believe in. Until you do, you will never be a writer, Eugene.

Later in the film...

Arnold (to Eugene): Once you start compromising your thoughts, you're a candidate for mediocrity.
