my life...its purpose

I wonder...
many times i heard this question, "what is the purpose of your life?" At the National Bookstore,in almost all, if not all branches, and even in department stores where they sell books, you will even see it displayed in their shelves this book that asked the same question. We only come across of that.. I, for one. Somehow, I wonder.. so, what could it be?
foolish question, some says. I also thought of that, actually. maybe... because in the first place, you never chose to live in this place called earth. So, how else could there be a purpose of your existence? Ok, so what is it then? Again, I wonder why...
Now, I got a problem.. to search for the answer to this question. Or is it?
And then, suddenly, I go back in time...Suddenly, I started evaluating myself...my life in the past.
What is good? Of course, during my toddler days, I don't remember anything but milk and toys... walking doll, in particular.. Seems like my childhood days were just like any other moments of being a kid. Just an ordinary kid. My mom and dad sent me to school.
