Last of all, we begin to sight the general bourne of the race of man. Fools that we are, we believe this bourne to be a dangerous reef; but it is the harbour, where we must some day put in, which we may never refuse to enter; and if a man has reached this harbour in his early years, he has no more right to complain than a sailor who has made a quick voyage. For some sailors, as you know, are tricked and held back by sluggish winds, and grow weary and sick of the slow-moving calm; while others are carried quickly home by steady gales. You may consider that the same thing happens to us: life has carried some men with the greatest rapidity to the harbour, the harbour they were bound to reach even if they tarried on the way, while others it has fretted and harassed.
The quote: To such a life, as you are aware, one should not always cling. For mere living is not a good, but living well. Accordingly, the wise man will live as long as he ought, not as long as he can.
He will mark in what place, with whom, and how he is to conduct his existence, and what he is about to do. He always reflects concerning the quality, and not the quantity, of his life. As soon as there are many events in his life that give him trouble and disturb his peace of mind, he sets himself free. And this privilege is his, not only when the crisis is upon him, but as soon as Fortune seems to be playing him false; then he looks about carefully and sees whether he ought, or ought not, to end his life on that account.
