Life, why be Futile?

This poem entails my pessimist side of viewing life, and the labyrinth it brings into my mind.

O life
How useless thou art
What means to be with thee
If you'll leave me then

Child schools, boy learns
Man knows, person understands
But no matter how much he knows
In his grave,
His brain rots, knowledge fades

Man works, he labors
Father earns, one succeeds
But no matter how much he gains
In his grave,
He can't bring even a coin.

Life is futile
We earn many, we strive to get
We almost kill ourselves to attain each
Have we asked, however
Will these last forever?

When life ends,
Everything we earn, everything we learn
Shall banish to nothing
Then one day we'll understand
WE HAVE NOTHING.
