But this is not what I started to write about. A great many men carry their life as an author carries a book which he is writing-- never losing the sense of their burden. When a writer undertakes a book, and feels the necessity of perfect continuity of thought and symmetry of structure, he can never lay it wholly aside. When once he has taken up the first chapter, and comprehended his materials and machinery and end, he does not dare to lay down his work, or diverge from the grand channel of his thought, until the last chapter is finished. He can take no three months' vacation; he can read no books that do not contribute to his progress in the chosen direction; he can never wholly lay aside the burden that is on him. It is like lifting upon one's shoulder the end of a long pole, and then walking under it from end to end. The burden upon the shoulder is not relieved until the whole length has been passed, and it drops as we walk from under it. Such is the way that many men, and, perhaps, most men, carry life. If their business troubles them, they have no power to throw it off, and no disposition to try to do it. They are entirely aware that they gain nothing by carrying their tedious burden, but they carry it. Not content with doing their duty, and trying their best while actively engaged, they take home with them a long face, breathe sighs around them in the saddest fashion, and really unfit themselves for the healthy exercise of their reason, and the active employment of their faculties. With men of this stamp, it makes little difference whether they are prosperous or otherwise. If times are good, and they really have no fault to find with matters as they exist, they become troubled about bad times that may possibly lie just ahead. "Oh, it's all well enough to-day," they say, "but you can't tell what is coming;" so they bind the burden of the future upon them, and undertake to steal a march on God's providence. Such a thing as doing the duty of a single day, and doing it well, and then throwing off the burden of care, and having a good time in some rational way, until the hour comes for the commencement of the next day's duty, they are strangers to. They walk into their houses with a cloud upon their faces. They have no words of cheer for those whom they have left at home during the day. They are moody and sullen and sad--absorbed by their troubled thoughts-- taking no interest in the schemes, and having no sympathy with the trials, of their wives and children, and making no effort to relieve themselves of their burdens. If they pray at all, they practically pray like this: "Give us this day our daily bread, and to-morrow, and next day, and the day after, and next year, and fifty years to come; and lest Thou shouldst forget it, or neglect to answer us, we have undertaken to look after the matter ourselves."
