Marcus Aurelius

Whatever the universal nature assigns to any man at any time is for the good of that man at that time.

You must become an old man in good time if you wish to be an old man long.

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.

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

Waste no more time arguing about what a good man should be. Be one.
