I think both you guys (lhotseface and deowl) are hitting different points:
deowl - You're saying that one cannot distinguish onself by having unique career goals, its your background that should distinguish you from other applicants.
lhotseface - You are saying that you cannot have any advantage by making your goals very broad and general. Rather tie it to your background and explain why you want to do what you want to do....
...now did I crack this case or what
I believe its yogurt!
