“Therefore, my daughter, be careful and diligent in all your affairs; God, Who commits them to you, wills you to give them your best attention; but strive not to be anxious and solicitous, that is to say, do not set about your work with restlessness and excitement, and do not give way to bustle and eagerness in what you do; every form of excitement affects both judgment and reason, and hinders a right performance of the very thing which excites us.”
