Radical youth is apt to long for some supreme sacrifice and feels that a lesser surrender is worth nothing. But better than sacrifice is efficiency! It is absurd to stand perplexedly waiting for the great occasion, unwilling to make the little efforts and test the little occasions, and unwilling to work at developing the power that would make those occasions great. Of all the roads of activity that lie before the youth at the threshold of life, one paramount road must be taken. This fear that one sees so often in young people, that, if they choose one of their talents or interests or opportunities of influence and make themselves in it “competent ones of their generation,” they must slaughter all the others, is irrational. It is true that the stern present demands singleness of purpose and attention. A worthy success is impossible to-day if the labor is divided among many interests. In a more leisurely time, the soul could encompass many fields, and even to-day the genius may conquer and hold at once many spiritual kingdoms. But this is simply a stern challenge to us all to make ourselves geniuses. For serious and sincere as the desire of radical youth may be to lead the many-sided life, a life without a permanent core of active and productive interest, of efficient work in the world, leads to dilettantism and triviality. Such efficient work, instead of killing the other interests of life, rather fertilizes them and makes them in turn enrich the central activity. Instead of feeding on their time, it actually creates time for the play of the other interests, which is all the sweeter for its preciousness.
