It's just an exercise in introspection, or as some describe it, navel gazing. Not everyone is interested and that's ok. However I have found over the years that those that are the most stubborn, opinionated and sometimes overly impressed with themselves are the very ones who abhor looking at themselves in a mirror. Or letting anyone else do it, knowingly. Essentially it's a defence mechanism and that's just fine. Live and let live.
Churchill was certainly all of the above but when he heard the others analysis he at first rejected it, but once it sunk in he knew it to be true and affected him deeply.
I was, maybe still am, all the above but in my senior years have been able to view myself in a different light with the help of others. It's not always pretty but once I and the people I was chatting with compared what they knew of me and how my work evolved over the years there was certain photographic themes that mirrored what was going on in my life. Our art is the mirror of our souls whether we like it our not. As Matt said it's all about communication. Each art image we make has a bit of our DNA in it.
If you don't like my post or don't want to participate, just put it on ignore and let those that want to explore things do just that.
