@Setanta,
Yeats is indeed the Bard of the century, a favorite of mine as well.
Here's a favorite - selections from "Vacillation"
My fiftieth year had come and gone,
I sat, a solitary man,
In a crowded London shop,
An open book and empty cup
On the marble table-top.
While on the shop and street I gazed
My body of a sudden blazed;
And twenty minutes more or less
It seemed, so great a happiness,
That I was blessèd and could bless.
....
Get all the gold and silver that you can,
Satisfy ambition, animate
The trivial days and ram them with the sun,
And yet upon these maxims meditate:
All women dote upon an idle man
Although their children need a rich estate;
No man has ever lived that had enough
Of children’s gratitude or woman’s love.
.....
No longer in Lethean foliage caught
Begin the preparation for your death
And from the fortieth winter by that thought
Test every work of intellect or faith,
And everything that your own hands have wrought
And call those works extravagance of breath
That are not suited for such men as come
proud, open-eyed and laughing to the tomb
