Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present. Marcus Aurelius
Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life. Marcus Aurelius
Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them. Marcus Aurelius
The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature. Marcus Aurelius
