My Head Is A Puzzle

My head is a puzzle
I can never fix
Pieces scattered everywhere
Full of dirty tricks
It knows all my secrets
It knows everything
What do I know about it?
Absolutely nothing!
Is there a single way
To take back my freedom?
Is there a single clue
To solve this conundrum?
Until I find an answer
I am forever stuck
Who is to be blamed for this?
Nobody but my luck
