Letter 23 — On the True Joy Which Comes from Philosophy (§8)

“There are only a few who control themselves and their affairs by a guiding purpose; the rest do not proceed; they are merely swept along, like objects afloat in a river. And of these objects, some are held back by sluggish waters and are transported gently; others are torn along by a more violent current; some, which are nearest the bank, are left there as the current slackens; and others are carried out to sea by the onrush of the stream. Therefore, we should decide what we wish, and abide by the decision.”
