I'm intensely curious what you have in mind for an 'Identity Challenge". I for one have a pretty darn good understanding of who I am, not entirely complete because this part of the journey isn't over yet, but a very good one none the less. However I'm unsure if it is something I could ever articulate...I think that degree of clear expression would require some form of telepathy...and I ain't got that'n figured out yet.
But I'm always game for a challenge!!
