"The more you are like yourself, the less you are like anyone else, which makes you unique." - Walt Disney
It's kind of cute the way he defines authenticity, as "being like oneself", rather than the more usual "being oneself". It makes it as something to be attainable and something that admits of degrees "the more you... the less you...", but as something to be attained. He knew it, because he did it!
