Bonus epigraph, for something

Already how am I so far
Out of that minute? Must I go
Still like the thistle-ball, no bar,
Onward, whenever light winds blow,
Fixed by no friendly star?

Just when I seemed about to learn!
Where is the thread now? Off again!
The old trick! Only I discern—
Infinite passion, and the pain
Of finite hearts that yearn.

--Browning, "Two in the Campagna," stanzas XI and XII
