A quote
In fine, to express my thoughts in brief compass and portray to you those busybodies and self-tormentors—they are as uncontrolled in the midst of their troubles as they are before them. He suffers more than is necessary, who suffers before it is necessary; such men do not weigh the amount of their suffering, by reason of the same failing which prevents them from being ready for it; and with the same lack of restraint they fondly imagine that their luck will last for ever, and fondly imagine that their gains are bound to increase as well as merely continue.
