By considering the love of God, we are inspired to set aside every worldly attachment and love God in return.
This is what makes the Rosary a "school of prayer" -- by praying the Rosary, we learn how to pray. The Rosary focuses on the love that God has revealed in the essential mysteries of our Lord's life, and moves us to imitate the love of Jesus. The Rosary is nothing more than the Scriptures: Both in the prayers and in the meditations.
St Louis Marie de Montfort recommends that you pray all fifteen decades of the Rosary every day, and I also recommend this. Be grateful to God for whatever devotion you have for the Rosary, and for however many decades you already prayer regularly! If we pray even one decade daily with much love, I am convinced that our Lady will lead us to praying all fifteen decades regularly.
