want & need

I really hv no idea on what Life is all about . Why we do what we do & why we do it ? Whats the purpose of Life really is? What is the definition of a perfect @ good life? Having a perfect family ? Loads of money? Power in hand? I cant justify anything in my life right now.

I have a good relationship with my family. Well thats what I think :) but sometimes I feel I'm still missing something in my life. And I have no clue what it is? I kept on thinking what I want in life but its actually what I need in life . Like a quote I've heard b4 ' its not what u want, its what u need, when u know what u need, u'll know what u want. ' ..but somehow , i cant even manage to think what I need too.. haha ~~

Do u know what u want and need?
