_Then I said, I have labored in vain, I have spent my strength for naught, and in vain_.–ISA. xlix. 4.

Because I spent the strength Thou gavest me In struggle which Thou never didst ordain, And have but dregs of life to offer Thee– O Lord, I do repent.
SARAH WILLIAMS.
Mind, it is our best work that He wants, not the dregs of our exhaustion. I think He must prefer quality to quantity.
GEORGE MACDONALD.
If the people about you are carrying on their business or their benevolence at a pace which drains the life out of you, resolutely take a slower pace; be called a laggard, make less money, accomplish less work than they, but be what you were meant to be and can be. You have your natural limit of power as much as an engine,–ten-horse power, or twenty, or a hundred. You are fit to do certain kinds of work, and you need a certain kind and amount of fuel, and a certain kind of handling.
GEORGE S. MERRIAM.
In your occupations, try to possess your soul in peace. It is not a good plan to be in haste to perform any action that it may be the sooner over. On the contrary, you should accustom yourself to do whatever you have to do with tranquillity, in order that you may retain the possession of yourself and of settled peace.
MADAME GUYON.
