Marcus Aurelius:

Of human life the time is a point, and the substance is a flux, and the
perception dull, and the composition of the whole body subject to
putrefaction, and the soul a whirl, and fortune hard to divine, and fame a
thing devoid of judgment.  And, to say all in a word, everything which
belongs to the body is a stream, and what belongs to the soul is a dream
and vapour and life is a warfare and a stranger's sojourn, and the after-fame
oblivion.  (III, 17)

The universe is transformation: life is opinion.  (IV, 3)

Wipe out imagination.  Stop the pulling of the strings.  Confine
thyself to the present....  Let the wrong which is done by a man stay
there where the wrong was done.  (VII, 29)

If thou art pained by any external thing, it is not this thing that disturbs
thee, but thy own judgment about it.  And it is in thy power to wipe out
this judgment now.  (VIII, 47)

No longer talk at all about the kind of man that a good man ought to
be, but be such.  (X, 16)
