The Pisan Cantos

On my nightstand is a folded piece of paper given to me by Fiona Templeton when she was here reading her latest work. On the paper is the following:

To have, with decency, knocked
That a Blunt should open
To have gathered from the air a live tradition
or from a fine old eye the unconquered flame
This is not vanity.
Here error is all in the not done,
all in the diffidence that faltered...

These lines are from Ezra Pound's Pisan Cantos 81.168-74.

"Here error is all in the not done". Should this be informing my wish to sleep this day into tomorrow?
