But then, man looks before and after, and has the terrible gift that by anticipation and by memory he can prolong the sadness. The proportion of solid matter needed to colour the Irwell is very little in comparison with the whole of the stream. But the current carries it, and half an ounce will stain miles of the turbid stream. Memory and anticipation beat the metal thin, and make it cover an enormous space. And the misery is that, somehow, we have better memories for sad hours than for joyful ones, and it is easier to get accustomed to 'blessings,' as we call them, and to lose the poignancy of their sweetness because they become familiar, than it is to apply the same process to our sorrows, and thus to take the edge off them. The rose's prickles are felt in the flesh longer than its fragrance lives in the nostrils, or its hue in the eye. Men have long memories for their pains as compared with their remembrance of their sorrows. So it comes to be a piece of very homely, well-worn, and yet always needful, practical counsel to try not to magnify and prolong grief, nor to minimise and abbreviate gladness. We can make our lives, to our own thinking, very much what we will. We cannot directly regulate our emotions, but we can regulate them, because it is in our own power to determine which aspect of our life we shall by preference contemplate. Here is a room, for instance, papered with a paper with a dark background and a light pattern on it. Well, you can manoeuvre your eye about so as either to look at the black background--and then it is all black, with only a little accidental white or gilt to relieve it here and there; or you can focus your eye on the white and gold, and then that is the main thing, and the other is background. We can choose, to a large extent, what we shall conceive our lives to be; and so we can very largely modify their real character. 'There's nothing either good or bad But thinking makes it so.' They who will can surround themselves with persistent gladness, and they who will can gather about them the thick folds of an everbrooding and enveloping sorrow. Courage, cheerfulness, thankfulness, buoyancy, resolution, are all closely connected with a sane estimate of the relative proportions of the bright and the dark in a human life. II. And now consider, secondly, the inclusion of the 'moment' in the 'life.'
