Marcus Aurelius

“You have power over your mind - not outside events. Realize this, and you will find strength.”

“Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.”

“To live happily is an inward power of the soul.”

“Because your own strength is unequal to the task, do not assume that it is beyond the powers of man; but if anything is within the powers and province of man, believe that it is within your own compass also.”

“How much time he saves who does not look to see what his neighbor says or does or thinks.”

“Time is a sort of river of passing events, and strong is its current no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away.”
