This month marks the 16th anniversary of the terrorist attacks on 9/11. Every year, Americans find themselves re-living the emotions and imagery of that day through social media and news reports. Naturally, on the anniversary, many people use social media to share their memories from that day including what they were doing, where they were, and how it changed their lives. As time passes, and I add more people to my network of friends and colleagues, I realize that every year I hear new stories of heroism from average people on that day.
