“The self-indulgent man craves for all pleasant things... and is led by his appetite to choose these at the cost of everything else.”
― Aristotle, The Nicomachean Ethics

“Gratitude goes beyond the 'mine' and 'thine' and claims the truth that all of life is a pure gift. In the past I always thought of gratitude as a spontaneous response to the awareness of gifts received, but now I realize that gratitude can also be lived as a discipline. The discipline of gratitude is the explicit effort to acknowledge that all I am and have is given to me as a gift of love, a gift to be celebrated with joy.”
― Henri J.M. Nouwen

“The real difference in the believer who follows Christ and has mortified his will and died after the old man in Christ, is that he is more clearly aware than other men of the rebelliousness and perennial pride of the flesh, he is conscious of his sloth and self-indulgence and knows that his arrogance must be eradicated. Hence there is a need for daily self-discipline.”
― Dietrich Bonhoeffer, The Cost of Discipleship

“Not everyone can have the same devotion. One exactly suits this person, another that. Different exercises, likewise, are suitable for different times, some for feast days and some again for weekdays. In time of temptation we need certain devotions. For days of rest and peace we need others. Some are suitable when we are sad, others when we are joyful in the Lord.”
― Thomas à Kempis, The Imitation of Christ
