It is less hurtful to take the chances of misfortune as a theme for speculation; because, in doing so, we provide ourselves at once with measures of precaution against it, and a pleasant surprise when it fails to make its appearance.  Is it not a fact that we always feel a marked improvement in our spirits when we begin to get over a period of anxiety?  I may go further and say that there is some use in occasionally looking upon terrible misfortunes—­such as might happen to us—­as though they had actually happened, for then the trivial reverses which subsequently come in reality, are much easier to bear.  It is a source of consolation to look back upon those great misfortunes which never happened.  But in following out this rule, care must be taken not to neglect what I have said in the preceding section.

SECTION 15.  The things which engage our attention—­whether they are matters of business or ordinary events—­are of such diverse kinds, that, if taken quite separately and in no fixed order or relation, they present a medley of the most glaring contrasts, with nothing in common, except that they one and all affect us in particular.  There must be a corresponding abruptness in the thoughts and anxieties which these various matters arouse in us, if our thoughts are to be in keeping with their various subjects.  Therefore, in setting about anything, the first step is to withdraw our attention from everything else:  this will enable us to attend to each matter at its own time, and to enjoy or put up with it, quite apart from any thought of our remaining interests.  Our thoughts must be arranged, as it were, in little drawers, so that we may open one without disturbing any of the others.

In this way we can keep the heavy burden of anxiety from weighing upon us so much as to spoil the little pleasures of the present, or from robbing us of our rest; otherwise the consideration of one matter will interfere with every other, and attention to some important business may lead us to neglect many affairs which happen to be of less moment.  It is most important for everyone who is capable of higher and nobler thoughts to keep their mind from being so completely engrossed with private affairs and vulgar troubles as to let them take up all his attention and crowd out worthier matter; for that is, in a very real sense, to lose sight of the true end of life—­propter vitam vivendi perdere causas.

Of course for this—­as for so much else—­self-control is necessary; without it, we cannot manage ourselves in the way I have described.  And self-control may not appear so very difficult, if we consider that every man has to submit to a great deal of very severe control on the part of his surroundings, and that without it no form of existence is possible.  Further, a little self-control at the right moment may prevent much subsequent compulsion at the hands of others; just as a very small section of a circle close to the centre may correspond to a part near
