29. God Demands Vigorous and Earnest Efforts—Put your highest powers into your effort. Call to your aid the most powerful motives. You are learning. Endeavor to go to the bottom of everything you set your hand to. Never aim lower than to become competent in the matters which occupy you. Do not allow yourself to fall into the habit of being superficial and neglectful in your duties and studies; for your habits will strengthen and you will become incapable of anything better. The mind naturally learns to be satisfied with that which requires little care and effort, and to be content with something cheap and inferior. There are, young men and young women, depths of knowledge which you have never fathomed, and you are satisfied and proud of your superficial attainments. If you knew much more than you do now, you would be convinced that you know very little.
(3BC 1161.8)
God demands of you vigorous and earnest intellectual efforts, and with every determined effort, your powers will strengthen. Your work will then always be agreeable, because you will know that you are progressing. You can either become accustomed to slow, uncertain, irresolute movements, so much so that the work of your life will not be one-half what it could be; or, your eyes fixed upon God, and your soul strengthened by prayer, you can overcome a disgraceful “slowness” and a dislike for work, and train your mind to think rapidly and to put forth strong efforts at the proper time. If your highest motive is to labor for wages, you will never, in any position, be qualified to carry high responsibilities, never be fit to teach (Manuscript 24, 1887).
