"This is no time for playing games. Nothing is as encouraging as when virtues are visibly embodied in the people around us. How soon will time cover all things, and how many it has covered already. What is long-lasting is not necessarily eternal. Nowhere can man find a quieter or more untroubled retreat than in his own soul. When someone is properly grounded in life, they shouldn't have to look outside themselves for approval. To understand the true quality of people, you must look into their minds, and examine their pursuits and aversions. The universe is transformation: life is opinion. Look back over the past, with its changing empires that rose and fell, and you can foresee the future too. Think of yourself as dead. You have lived your life. Now, take what's left, and live it properly. Very little is needed to make a happy life; it is all within yourself, in your way of thinking. Remind yourself that what is past is nothing. Everything that exists is in a manner the seed of that which will be. Adapt yourself to the life you have been given; and truly love the people with whom destiny has surrounded you."

Marcus Aurelius Roman Emperor
