Undergraduate / Stanford "Intellectually engaging idea" Essay [6]

I've just started and was wondering what you guys think of this topic...

What is the ultimate purpose of my existence in this world? What niche do I have to fill in my life? Questions like these have puzzled me persistently for many years. Now especially, as I search for my ideal college, the perfect major, a profitable career, and the correct path in life, I find it difficult to comprehend my function in this universe of infinite possibilities.

Thanks,
