The rosary is such a powerful prayer. Every time I say it I feel as though my soul is strengthened. Unfortunately, I frequently forget part of it. I just found a beautiful Rosary "cheat sheet" that has all the prayers on it in one easy page.
My mind wanders when I try to pray the rosary and I found that this link http://www.rosary-center.org/howto.htm helps me to stay focused on meditating on each mystery. (On the top of the page each mystery is listed. )
