Boxed in!

This is how a day in my weekday looks like:

I saw that green sign in the corridor - "Exit", and next to the word there is a green man running towards the door.
Its all I could see .... Exit
Conversation running in my mind when i comeback to my desk which is in a box and stare into my comp which is a box..
"What am I doing"
"Where am I going"

I sit in a box, look at one 12 hours a day and then go home to a box.
My mind is in a box, locked up somewhere and someone threw away the keys.
How am I investing 12 hours a day into something that is sucking my mind out.
Welcome to my mind - on edge, almost dead and completely tired!
