Seth Godin has a very interesting post this morning on what it means to be authentic.
Authenticity, for me, is doing what you promise, not "being who you are".
Seth says “being” is amorphous and internal vision is always blurry. What he’s really saying is that what you do will always speak more loudly than what you say. At least it ALWAYS has for me, and generally not to my credit or benefit.
But I’m working on it.
