God, give us grace to accept with serenity the things that cannot be changed, courage to change the things that should be changed, and the wisdom to distinguish the one from the other.
In all times of emotional disturbance or indecision, we can pause, ask for quiet, and in the stillness simply say: “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. Thy will, not mine, be done.”
