Letras:Nine Inch Nails. Discipline.

:
Am I still tough enough?
Feels like i?m wearing down
Is my visciousness
Losing ground?
Am I taking too much?
Did I cross a line?
I need my role in this
Very clearly defined

I need your discipline
I need your help
I need your discipline
You know once I start I cannot help myself

And now it's starting up
Feels like I'm losing touch
Nothing matters to me
Nothing matters as much
I see you left a mark
Up and down my skin
I don't know where I end
And where you begin

I need your discipline
I need your help
I need your discipline
You know once I start I cannot help myself

Once I start I cannot stop myself
