Thinking of this in the Haven sense, I've rather liked Reinhold Niebuhr's serenity prayer in tough times:
God grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference.

“Love takes off the masks that we fear we cannot live without and know we cannot live within. I use the word "love" here not merely in the personal sense but as a state of being, or a state of grace - not in the infantile American sense of being made happy but in the tough and universal sense of quest and daring and growth.” - James Baldwin
