If you haven't read any of Malcolm Gladwell's books, I would recommend those. I loved "The tipping point" and "Blink".
Freakonomics is another interesting look at interesting statistics (but without the jargon!).
I also recently read "Secrets of great marriages" by Charlie and Linda Bloom. Even if you are not married, it has wonderful stories about what it takes to make and maintain great relationships.
"Al-Ghazali: The ninety-nine beautiful names of God" translated by David Burrell and Nazih Daher was also very good for many points to reflect on.
