The Rosary is a wealth of prayers that help us meditate on the life, death, and resurrection of our Lord, Jesus Christ. If you really want to change your life, than you can’t go wrong with a regimen of prayers like that of the Rosary. If you need some divine assistance, Mary the Mother of God will intercede for you just as she did for the Wedding Feast at Cana. Mary always leads us to Jesus.
Here is a great video with all the prayers and instructions for beginners: http://www.catholic.org/prayers/rosary.php
