WANTS AND HAPPINESS

Sometimes I dont understand what is this all for?
Why we run all the time behind "MATERIAL THINGS"?
Why is this "Greed"?
OR why it is always that we have everything we need, but not what we want?
Even if that is not so big, may be just emotions, no money need to buy that.

THEN?
Why always there is something which human complain?
Why we always lack something to make others happy?
Why we always complain even after others put all the efforts they can, to make us happy?
May be because we evaluate others from our eyes and others always do what they think is right rather than finding out what their loved ones want?
What make that person happy?

The whole emotional drama is for happiness,
We put efforts everyday but remain unsuccessful.
I think te whole game is of
EMOTION
CARE
LOVE
BUT, all one gets is criticism for NOT being
EMOTIONAL
CARING
LOVING.
Is this true? if everyone carves for the same?
Questions are so much and answer are none.
