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.
Henri NouwenWe can be unhappy about many things, but jy can still be there... It is important to become aware that at every moment of our life we have an opportunity to choose joy... It is in the choice that our true freedom lies, and that freedom is, in the final analysis, the freedom to love.
Henri Nouwen
