Where your pleasure is, there is your treasure; where your treasure is, there is your heart; where your heart is, there is your happiness. (Augustine, 4th century theologian)
What makes you happy? What gives you the most pleasure? Is it something you can share with others, or do you enjoy it only in private? Because happiness is so transient, we all need to find worthwhile activity to enjoy, especially with family and friends. And there is another dimension, too. A heart focused on spiritual realities can provide a deep, abiding happiness and joy.
Above all else, guard your heart, for it is the wellspring of life (Proverbs 4:23).
