Marcus Aurelius Quote
"Well then, remember to take those little vacations into yourself. Whatever you do, don't be troubled or anxious, but be free, and look at things like a man, a human being, a citizen, a part of the creation that must die. Chief among the thoughts close at hand, keep these two: first, that nothing outside the mind can disturb it - trouble comes from the mind's opinion of what lies outside it; and second, that everything you now see will change in a moment and soon be no more. Can you even begin to count the changes you have already witnessed?
This world is change; this life, opinion."
