If you’ve read any magazines, Web sites, newspapers, or books in the last decade, you probably know who I am. You know I have a three-second attention span, because I was weaned on emails, texts, and instant messages. You know I’m a self-esteem junkie, because I got participation trophies when I played little-league baseball. You know I’m totally narcissistic, because I have a Facebook page, and a Twitter account, and a Last.fm profile. And you know the buzzword that’s being tossed around to describe me and the other 92 million 9- to 29-year-olds who are theoretically just like me: Millennials.
