An Anonymous Poem with a Brilliant Twist

"Today was the absolute worst day ever
And don't try to convince me that
There's something good in every day
Because, when you take a closer look,
The world is a pretty evil place
Even if
Some goodness does shine through once in a while
Satisfaction and happiness don't last.
And it's not true that
It's all in the mind and the heart
Because
True happiness can be obtained
Only if one's surroundings are good
It's not true that good exists
I'm sure that you can agree that
The reality
Creates
My attitude 
It's beyond my control
And you'll never in a million years hear me say that
Today was a good day"
