text: But it is hard to keep within bounds in that which you believe to be good. The real good may be coveted with safety. Do you ask me what this real good is, and whence it derives? I will tell you: it comes from a good conscience, from honourable purposes, from right actions, from contempt of the gifts of chance, from an even and calm way of living which treads but one path. For men who leap from one purpose to another, or do not even leap but are carried over by a sort of hazard, – how can such wavering and unstable persons possess any good that is fixed and lasting? 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.
