everyone has a purpose in life and i'm sure one of you has something to share :)
I want to be a successful businesswoman in the future and be fluent in as many languages as possible :D
Great sentiments from those above.
I think this is the definitive answer to the question from Monty Python:
There is a Steve Martin movie called "The Jerk" that sums it up quite nicely.
Idealistic purpose: To make a difference in the world. Not to change an entire world, but just enough so that you know that you made a positive change in someone's life.
My purpose is to get through school and become a Surgeon to help people.
