This one has always helped me when down in blues…
’Tis not too late to seek a newer world.
Push off, and sitting well in order smite The sounding furrows;
for my purpose holds To sail beyond the sunset,
and the baths Of all the western stars until I die.
It may be that the gulfs will wash us down:
It may be we shall touch the Happy Isles,
And see the great Achilles, whom we knew.
Tho’ much is taken, much abides; and tho’
We are not now that strength which in old days
Moved earth and heaven; that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.
