The following is from St. Robert Bellermine, SJ. My middle name is "Robert", so perhaps that has something to do with why this quote appeals to me. However, I think it is the thought so succinctly expressed. Enjoy!
"If you are wise, then know that you have been created for the glory of God and your own eternal salvation. This is your goal; this is the center of your life; this is the treasure of your heart. If you reach this goal, you will find happiness. If you fail to reach it, you will find misery."
