I received this response from Tristan Bishop, through Facebook.

"My defining moment was last year, when I listened to encouragement from several mentors I'd met on Twitter. I was scared to speak boldly within my company on the need for Social Media adoption, but knew it to be essential. Mike Henry told me to "lead from WHO you are, not from where you sit." The choice to heed that advice has made all the difference."
