what is life for? (english version)

in your opinion, what is the objective of life.... somebody may say it is like a wave that could threaten your life and somebody may say it is like a journey for you to go through.... i think that life is miserable that makes your life difficult. anyhow, how difficult your life is there is God going thru with you every second and wherever you go. recently there is a lot of things happening to me... include pressure of assignment, preparing for final exams, worried about little things and so on. but i know God is with me.
