St. Francis De Sales, Doctor of the Church advises you to cultivate affection for God's friends , the Saints so they will be your friends too.  On St. Valentine feast day chose a Saint to  get to know intimately through the course of the year.  
Let us follow the advice of this kindly bishop appealing to every Father, Mother and children and single folks to become the dearest friends for a whole year on one of the Saints you will chose.  Look to Echoes of Holiness Book to find the Ancient Saints for choice, if you like.
Or from the books on Saints on our book category.
