“Gratitude as a discipline involves a conscious choice. I can choose to be grateful even when my emotions and feelings are still steeped in hurt and resentment. It is amazing how many occasions present themselves in which I can choose gratitude instead of a complaint. I can choose to be grateful when I am criticized, even when my heart still responds in bitterness. I can choose to speak about goodness and beauty, even when my inner eye still looks for someone to accuse or something to call ugly.”
-Henri Nouwen
