問題詳情：

Your mind like your body is a thing where the powers are developed by effort．This is a principal use, as I see it，of hard work in studies．Unless you train your body you can’t be a good sportsman, and unless you train. your mind you can’t be much of a scholar．The four miles a boatman covers at top speed is in itself nothing to the good．but the physical capacity to hold out over the distance is thought to be of some value．So a good part of what you learn by hard study may not be kept forever．and may not seem to be of much final value．but your mind is a better and more powerful instrument because you have learned it．“Knowledge is power，”but still more the ability of obtaining and using knowledge is power．If you have a trained and powerful mind，you are certain to have stored it with something．its value is more in what it can do, what it can grasp and use，than in what it contains; and if it were possible，as it is not．to come out of college with a trained mind and nothing useful in it．you would still be ahead．and still, in manner, educated．
