And even where middle life has won success in the things men covet, and for which they strive, it may be the success that is just deadly in its reaction of monotony. How often do we hear it said of a prosperous man, who in middle years is giving place to unworthy habits, or to ill-humour and chronic depression: "Would he had something to take him out of himself; some interest in anything, if it were but a harmless hobby." Think of a man being reduced to the need of a "hobby" to keep him out of moral mischief! What such a man, if man he can be called, really needs is some higher interest or a coffin. A hobby is well enough in its place, and much can be said for it, but when it becomes a man's only peradventure between himself and the devil, the world can probably spare him to its own advantage. The young have no little safety in their years, in the temporary buoyancy of the blood. It is when the former draw in, and the latter thins out, that dangerous things get their more obvious and, too often, fatal chance with men. It is when the first fires of passion have slowed down, and the ties of early friendship have relaxed, and the outlook appears to leave us with the problem, not how to live, but how to exist. I tremble at times when my experience suggests the dangers of those long stretches of emptiness, that so easily fill with the sinister and the unspeakable. I would pray, as a man in mortal terror, against the bottomless pit of a motiveless existence. This is why I put emphasis upon the threshold of manhood; not that I believe it to be the most dangerous part of human life, but because I believe it is the time to safeguard the part that is. It is the time when habits can be cultivated, and resources acquired, which can make middle life as crowded with interest and good to enjoy as any of the earlier years, and infinitely more useful. But this is possible only when the middle years can command their own. Just as many of us "postpone life until after our funeral," so may we find ourselves in middle life discouraged and sullen because we cannot do what we would, only because we have not done what we ought. Men do not always go under because they cannot do things. They fail, not because they do not know what it is well to do, but because they do not choose to attempt it. And why do they not choose? So far as this question affects middle life, it is largely because so few of us have the grit to face its difficulties, and attack them, when we have to do it with the serious handicap of self-made disadvantages. It is while you are young that you must lay up these stores of living material for the after years; and this is the significance of it all--you can only do it, or you can do it most effectually, when you are young. As touching certain advantages, "the day after to-morrow is the only day that never comes."
