If the heart wanders or is distracted, bring it back to the point quite gently... And even if you did nothing during the whole of your hour but bring your heart back, though it went away every time you brought it back, your hour would be very well employed.
~ St. Francis de Sales in INTRODUCTION TO THE DEVOUT LIFE
Expressions of gratitude create in others an eagerness to reciprocate. When we become more fully aware that our success is due in large measure to the loyalty, helpfulness, and encouragement we have received from others, our desire grows to pass on similar gifts. Gratitude spurs us on to prove ourselves worthy of what others have done for us. The spirit of gratitude is a powerful energizer.
