Reading Lo Que Dices, Recibes, by Don Gossett. His sister gave it to him to read on his return trip home to Yuma, Arizona from Abalene, Texas. The book has a "Secretish" theme--if you speak negatively, you will get negatives back, he explained.
He was so dedicated to the book that he was using drops in his eyes so he could keep reading. The air conditioning on the bus, as well as the lights are hard on his eyes.
His favorite book--The Bible, specifically Proverbs.
