Vanessa - "This people honoureth me with their lips, but their heart is far from me." - mt 15:8 I do not recommend praying the rosary without charity. By that I mean speaking words without regard for their meaning or purpose. "Happy is the man" ... that "guides his words with discretion". If you do speak, "and have not charity, you become as sounding brass, or a tinkling cymbal". - 1 corinthians 13:1
So, I cannot recommend a habit of speaking loosely(even if the words are pious), it will spill over into other relations. That means that I don't like +Fellay's way of praying the rosary. He is a modernist. "Don't emulate evil doers, nor envy them that work iniquity".
I recommend and follow myself to a personal particular degree what miseremini posted. I particularly recommend that advice for sundays. These are our traditions. Also, I recommend that you keep together the order of the mysteries. I enjoy most the mysteries that I struggle comprehending with ease, because when I do grasp the concept/mystery, it is all the more enjoyable to pray. Be patient and pray to your guardian angel to bring to mind a profitable and correct intention/understanding suitable for an intercessory prayer("and love thy neighbor as thyself").
When praying the ave maria, I view it as such - a prayer(not a melody or meditation/instructional aid); it ends as such("ora pro nobis"). I meditate on the mystery before I begin my decade, but it is not uncommon that an inspiration or better understanding of the mystery introduces itself to me while I am reciting that particular decade. When that is the case, I welcome it; it makes it all the more enjoyable. I am generally cognizant of/focusing on the words.
