I have had Shakespeare's Sonnet 15 on my mind lately, particularly the final two lines:
And all in war with Time for love of you, As he takes from you, I engraft you new.
It expresses for me the small possibilities we have to redeem and make new. It is my antidote to the cultural message of the futility of effort. We are so small, and our lives so brief, and yet we can spin magic,
and love and heal and create.
