Marcus Aurelius Quotes:

• “How easy it is to repel and wipe away every impression which is troublesome or unsuitable, and immediately to be in all tranquility.”
• “Your mind will take the shape of what you frequently hold in thought, for the human spirit is colored by such impressions.”
• “The mind adapts and converts to its own purposes the obstacle to our acting. The impediment to action advances action. What stands in the way becomes the way.”
