At the risk of appearing predictable, the Bible was and remains the biggest influence on my thinking. I was raised reading it, memorizing passages from it and being guided by it. I still find it a source of wisdom, comfort and encouragement.
One of my favorite times was sitting reading quote books, which I did for hours on end.
