Mental Efficiency And Other Hints to Men and Women by Arnold Bennett Excerpt The above lines from Matthew Arnold are quoted by one of my very numerous correspondents to support a certain optimism in this matter of a systematic attempt to improve the mind. They form part of a beautiful and inspiring poem, but I gravely fear that they run counter to the vast mass of earthly experience. More often than not I have found that a task willed in some hour of insight can not be fulfilled through hours of gloom. No, no, and no! To will is easy: it needs but the momentary bright contagion of a stronger spirit than one's own. To fulfil, morning after morning, or evening after evening, through months and years--this is the very dickens, and there is not one of my readers that will not agree with me.
