" Remember always thine end, and how the time which is lost returneth not. Without care and diligence thou shalt never get virtue. If thou beginnest to grow cold, it shall begin to go ill with thee, but if thou givest thyself unto zeal thou shalt find much peace, and shalt find thy labour the lighter because of the grace of God and the love of virtue. "
