Another good read is a great book titled "Within" by Dr. Habib Sadeghi. Here's a quote; --
"It's difficult to be still when we live in a world where everyone's attention is so fractured. Concentration has become a lost art in the age of cell phones, portable computers, internet-on-demand, iPods, texting, Blackberries, electronic books, instant messaging, Twitter, blogging, Facebook, video games and Skype camera communication."
"As human beings, we're becoming more and more disengaged from one another. We're communicating more and saying less. Remember that the most important thing you can ever give anyone or anything is your attention!"
