Green Helmet: The Consolation William Butler Yeats

I had this thought awhile ago,
'My darling cannot understand
What I have done, or what would do
In this blind bitter land.'

And I grew weary of the sun
Until my thoughts cleared up again,
Remembering that the best I have done
Was done to make it plain;

That every year I have cried, 'At length
My darling understands it all,
Because I have come into my strength,
And words obey my call.'

That had she done so who can say
What would have shaken from the sieve?
I might have thrown poor words away
And been content to live.
