You have power over your mind, not outside events. Realize this, and you will find strength. — Marcus Aurelius. Roman emperor from 161 to 180
Be like the promontory against which the waves continually break, but it stands firm and tames the fury of the water around it.
Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe love nothing so much as to change. The Universe is change.
In the life of a man, his time is but a moment...his sense, a dim rushlight. All that is body is as coursing waters...all that is of the soul, as dreams, and vapors.
I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinion of himself than on the opinion of others.
