Since i spent my four years in high school at an all-girls Catholic school taken cared by nuns, i can say that it really had influence me when it comes to my spiritual life. There, we prayed a lot, had a regular catechism, read the bible/lives of saints, prayed the Angelus, station of the cross, attended mass every Sunday, prayed the rosary, have a scheduled confession and sing praises to God. I used to be a choir member then and we sang religious songs.
But after i graduated, those religious routine have been slowly diminished. But it doesn't mean to say that i already have forgotten about the teachings i learned from that school. I have taught my kids to pray before going to bed and say a prayer before and after meal. I still do attend mass every Sunday with my family, do a silent prayer before going to bed and after waking up. But i admit i don't pray the rosary that often.
I may not be a religious person but i still do my duties as a real Catholic. I place God above anything else. And i thank HIM for all the blessings i got everyday and turn to Him whenever i feel so down. God is good. Always. And He never abandons. Just have faith and He'll never put us down.
