Still with a lot left to give

I have mentioned before that my husband gave me a desk calendar with a poem for each day of the year. Today's is taken from Ulysses by Alfred Lord Tennyson, and I'd like to quote part of it for all of us with greying temples who feel sometimes that our best is well behind us:

Made weak by time and fate, but strong in will
To strive, to seek, to find and not to yield."
