Lenin:

Young people, particularly, need the joy and force of life. Healthy sport, swimming, racing, walking, bodily exercises of every kind, and many-sided intellectual interests. Learning, studying, inquiry, as far as possible in common. That will give young people more than eternal theories and discussions about sexual problems and the so-called ‘living to the full’. Healthy bodies, healthy minds I Neither monk nor Don Juan, nor the intermediate attitude of the German philistines. You know, young comrade –– ? A splendid boy, and highly talented. And yet I fear that nothing good will come out of him. He reels and staggers from one love affair to the next. That won’t do for the political struggle, for the revolution. And I wouldn’t bet on the reliability, the endurance in struggle of those women who confuse their personal romances with politics. Nor on the men who run petticoat and get entrapped by every young woman. That does not square with the revolution.
