Classicly

As the world breaks in on a boy with its crashing thunder, he has a feeling of expansion, of sudden wisdom and sudden care. The atoms of things seem to be disintegrating around him. Then come the tearings and the grindings and the wrenchings,[Pg 8] and in that conflict the radical or the poet is made. If the youth takes the struggle easily, or if his guardian angels have arranged things so that there is no struggle, then he becomes of that conservative stripe that we have renounced above. But if he takes it hard,—if his struggles are not only with outward material conditions, but also with inner spiritual ones,—then he is likely to achieve that gift of the gods, perpetual youth. The great paradox is that it is the sleek and easy who are prematurely and permanently old. Struggle brings youth rather than old age.
