Being truly authentic is actually No Fun. It means not matching, not fitting into anyone's pigeon hole. It means not caring if you're an outcast. It is by 'fitting in' that we get a job or a client. We are just as authentic as we can afford to be.

So, like [musician] Lana Del Ray – or don’t. But, as you make that very important determination, ask yourself how and why you reached it. And please, don’t use the word “authentic” to describe, well, anything. To quote the great Madonna (good thing she didn’t have any managers, right?), “We are living in a material world.” And you know what, it’s really not that bad.
