Grass is always greener on the other side

Shining in the distance
They see a beacon of happiness
It flashes and then is gone
Enticing them, exploiting weakness

So many seeking happiness,
yet none have a clue or trail
and if not found amid the world
they say its the "holy grail"

None content with what they have
Living like nomads, never do they bide
I hope its not too late when they realize
the grass is always greener on the other side
