When what we do we doesn't

I don't know if I'm qualified to say
What you might and what i may.
I don't know wherefore you go
And what you do, but success is not far
That at least you must know.
I'm grappling with troubles but
Enough of all that, what troubles
Beset you, and what you do doesn't:
That's a fact. I within burnst
More and pain, what is it I can do
Some one said you were playing so
I fell into a trap and now talk we mustn't,
What can we do, when what we do we doesn't.
