Obey without so much useless brooding… Showing sadness or reluctance when asked to do something is a very considerable fault. But just to feel like this is not only no fault, but can in fact be the opportunity for a great victory, for crowning an act of heroic virtue.

I have not invented this. Remember the Gospel tells us that a father asked his two sons to do the same job. And Jesus rejoices in the one who, despite raising difficulties, does it! He rejoices because discipline is the fruit of Love.
