Worry is evidence of an ill-controlled brain; it is merely a stupid waste of time in unpleasantness. If men and women practiced mental calisthenics as they do physical calisthenics, they would purge their brains of this foolishness.
I think it rather fine, this necessity for the tense bracing of the will before anything worth doing can be done. I rather like it myself. I feel it is to be the chief thing that differentiates me from the cat by the fire.
