"Our permanent life is full of temporary people."
"Others can stop you temporarily, you are the only one who can do it permanently."
"Remember, no human condition is ever permanent. Then you will not be overjoyed in good fortune, nor too sorrowful in misfortune."
"You cannot help people permanently by doing for them, what they could and should do for themselves."
"Nothing is permanent in this wicked world, not even our troubles."
