I was talking with someone the other night, and he said, "I was one of the first to use Wikipedia." When pressed, he confirmed, "Right at the beginning."
It's pretty obvious that he wasn't one of the first to use Wikipedia. He was one of the first people he knew who had used Wikipedia. Big difference.
People make their own realities. If Bill thought he was first, then in his mind, he was. When he started using it, it began to exist. When he stops going back, it will disappear.
Every person who encounters your organization for the first time comes with beginner's mind. She knows nothing about yesterday or how hard you worked or your financing or what it took to build it. She's here now, she's first, let's go.
