The 'advancing man' in medicine, who holds to a clear mental image of himself as successful, and who obeys the laws of faith, purpose, and gratitude, will cure every curable case he undertakes.
Wallace D. WattlesIn daily life we must see that it is not happiness that makes us grateful, but gratefulness that makes us happy. It is necessary, then, to cultivate the habit of being grateful for every good thing that comes to you, and to give thanks continuously. And because all things have contributed to your advancement, you should include all things in your gratitude.
