Similarly, although you must exert all your energy in trying to conquer your passions, vices and imperfections, and to became master of every kind of virtue, you must nevertheless, work at this without being carried away by your zeal. So that when you do not perceive in yourself as many virtues, or as much love of God as you would like to see, you may remain at peace and undisturbed, humiliating yourself because of the obstacles you yourself have placed in the path of virtue.--St. John Eudes, The Four Foundations of Sanctity
