Tho’ much is taken, much abides

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.

~ Part of the poem Ulysses, by Lord Alfred Tennyson

(True story: In the process of writing my latest book, I had to make thirteen trips to the ERs (emergency departments, actually) of three different hospitals. So this poem has some meaning to me.)
