Here is one of St. Jean Vianney's favorite stories that he would often tell in his homilies on the power of attending Eucharistic Adoration:
"A few years ago there died a man who belonged to this parish. Upon entering the church in the morning to pray before setting out for the fields, he left his work tools at the door and then became wholly lost in the presence of God while praying before the sacrament. A neighbor who worked close to him, and thus used to see him in the fields, worried at his unusual absence. On his way home he found the missing man’s tools outside the church, then entered the church to see if the missing man was ill inside. He did find him in the church. The man had been praying in front of the Blessed Sacrament all day. His friend in disbelief that he had missed his whole day asked him, “What have you been doing here all day?” The missing man replied, “I have been looking deeply into the good God’s face and He has been looking deeply into mine.”
