Beauty vanishes; virtue is lasting.
A purpose you impart is no longer your own.
Every situation--nay, every moment--is of infinite worth; for it is the representative of a whole eternity.
What is hardest of all? That which seems most simple: to see with your eyes what is before your eyes.
Great necessity elevates man, petty necessity casts him down
No one knows what he is doing so long as he is acting rightly; but of what is wrong one is always conscious.
