How far away the stars seem, and how far Is our first kiss, and ah, how old my heart! - William Butler Yeats

...
Those masterful images because complete
Grew in pure mind, but out of what began?
A mound of refuse or the sweepings of a street,
Old kettles, old bottles, and a broken can,
Old iron, old bones, old rags, that raving slut
Who keeps the till. Now that my ladder's gone,
I must lie down where all the ladders start
In the foul rag and bone shop of the heart.

Being Irish, he had an abiding sense of tragedy, which sustained him through temporary periods of joy.

Heaven blazing into the head:
Tragedy wrought to its uttermost.
Though Hamlet rambles and Lear rages,
And all the drop-scenes drop at once
Upon a hundred thousand stages,
It cannot grow by an inch or an ounce.
