LIFE-How to define it?

If you could call this poetry, well and good, but I just felt like writing this......

If,
Life is not education,
Life is not work,
Life is not a game,
Life is not a challenge,
Life is not a storm,
Life is not money,
Life is not a bed full of roses,
Life is not beautiful,
Life is not a journey,
Life is not a play,
Then
I ask you truly my friend, What is the definition of "LIFE"?
