what is the meaning of life?

For some, it's being a Supermodel:

This must be GA's most frequently-asked question.

I have the answer!

It is...

"to feel"

:)

I don't think $2 gets you an answer to this.

I don't think money is the issue.  As Albert Camus once said, "Moss is
Kate is Kate is Moss."  Enraged by this observation, Sartre is said to
have quipped, "Kate Moss?  She is the nothingness of being, the being
of nothingness, the Jean Paul Gaultier of existential despair, the
lipstick trace of a forgone conclusion nestling in the sad arbour at
the top of a vanished vedette's garter."  Or as Maigret opined, "Those
Reds?  We will frame them all in the end!"  That was immediately
before a prolonged silence after which all three characters engaged in
a furious fist fight (jam rag style) on the corner of the Boul Mich
and the Boulevard St Germain - Lord, how the feathers flew! - and just
at that moment, who should turn up in a disheveled state with both his
tiny and tidy hands in the pebble-filled pockets of an unfurled
pantaloon but Sam Beckett...

Was that a clue? 

If so, my guess is O-phosphoryl-4-hydroxy-N,N-dimethyltryptamine

The question is flawed. It assumes life can be defined, and once a
definition has been agreed on, it assumes that life has meaning.

Life is a process, not something with a meaning of itself.

For life to have a meaning requires some entity to have meant the
meaning. For the religious, this entity is God.

For the rest of us, there is no such entity therefore no meaning.

"The meaning of life differs from man to man, from day to day and from
hour to hour. What matters, therefore, is not the meaning of life in
general but rather the specific meaning of a person's life at a given
moment."
 
-- Viktor E. Frankl

i just read about this excercise in a website: you sit with a blank
piece of paper  and write something you think is the meaning of life,
you keep writing until something you write makes you cry.

havent tried yet do....

I don't think you can know the meaning of life, but you can understand
its purpose. The intent of life is discovery and growth in mind and
spirit. Life is eternal, and this time we spend as temporal beings is
a time of awe. There is nothing to dread about the meaning of it all.
It's a dance. Enjoy it.

The very fact that you're asking this question gives meaning to life.
