Success in every order is always attained on the same conditions: to reflect at the start, to begin at the beginning, to proceed methodically, to advance slowly, to give out all one’s strength. But the first object of initial reflection is to decide what we are fit for. The “Know thyself” of Socrates is not only the key to morality, but to every vocation, since to be called to something is to see our individual path marked out along the wide human road.
––A. G. Sertillanges, O.P., The Intellectual Life: Its Spirit, Conditions, Methods, translated by Mary Ryan
