The Importance of being Interested　　1) Now I have recalled these beginnings of the careers of Franklin, Darwin and Mozart because they strikingly illustrate a profound psychological truth the significance of which can scarcely be overestimated. 2) It is fl truth, to be sure, that has long been partially recognized. 3)But its full meaning has not been--and could not be—appreciated until quite recently. 4)Only within the past few years has scientific research effected various discoveries which make its complete recognition possible and of supreme importance—of such importance that practical application of the principles involved would make for an immediate and stupendous increase in human happiness, efficiency, and welfare. 5)Stated briefly, the truth in question is that success in life, meaning thereby t he accomplishment of results of real value to the individual and to society, depends chiefly on sustained endeavor springing out of a deep and ardent interest in the tasks of one's chosen occupation.
