"What is it in the end, that induces a person to go his/her own way and to rise out of unconscious identity with the mass as out of a swathing mist? Not necessity, for necessity comes to many, and they all take refuge in convention. Not moral decision, for nine times out of ten we decide for convention likewise. What is it, then that inexorably tips the scales in favor of the extra-ordinary? It is what is commonly called vocation: an irrational factor that destines a person to emancipate him/herself from the herd and from its well-worn path."
