That's the latest incarnation of that piece of nonsense. When I was younger it was Be Yourself.
OK, How do I not be myself?
How do I be someone else?
I really fancy being,... Cindy. OK, tell me how to be Cindy because if it is possible for me to not be myself, to not be authentic, then by logical progression, it must be possible for me to be other people.
And right now, I kinda fancy being a super popular Ozzi, living somewhere it's actually warm.
