Yeats

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.
