Hello Ashish8,
How funny you should ask -- I just wrote a blog post on the career goals essay today! It should be up on the BeatTheGmat blog network.
But to save you from clicking around, I would answer in one word:
FOCUS. Even if many students navigate away from the choice they wrote about on their application, you would do well to put together a clear plan toward a specific long-term objective. Schools want to know that you have thought the through what you want to do. They want to know that you can figure out how to get from A to B.
Many schools want you to connect your personal experience with your career goals. That doesn't necessarily mean that you have to be in the same field (it is absolutely ok to switch careers); it means you have to connect what kind of person you are and what kind of experiences you have had as a foundation for what you want to do. Harvard calls this your career "vision" -- Stanford asks about your "career aspirations." Personally, I like Duke Fuqua's phrasing, which asks "Describe your vision for your career, your inspiration for pursuing this career path?" That covers a lot of ground!
It's good to be asking these questions now -- that gives you time to think things through and consider the many career paths in front of you.
Good luck!
