Why isn't anyone happy?

Is it because we believe sadness perpetual
believe we ought to be person 'x', 'y', and 'z'
instead of person 'me'

Is it because happiness is made up of so many factors
where the absence of one makes us sad overall

Is it because we fail to accept that lack of effort is the only real failure
and that a pass or fail on a sheet of paper is nedver
a true unit of measure of the person you are

Do we look at others to much
and misinterpret them, think them happy
so that we then feel like the scum humanity?

Is happiness the greatest falacy
ahead of religion maybe
we imprison ourselves and then complain to those...
who don't hold the key.
