First Impression 6.0

I'm confident asserting that the fundamental aspects of my personality - especially my temperament - haven't shifted much over my lifetime. How about you? Putting aside behavioral changes you've made to help you better navigate the world, would you say you've remained much the same person over your lifetime? Or would you claim you're fundamentally different? In what way? 

Still, assuming I am - as I believe - much the same now as I've always been, I'm just as confident saying that the first impression I make on others has shifted radically over my seventy-six years. And in my case, that's been a good thing. How about this element of your make-up? Has the first impression you make on others changed a great deal over your lifetime? If your answer is no, I'm guessing you either don't care about the first impression you make on others or, you've been largely satisfied with how things have gone for you in that respect and have stayed the course. 

But if like me you've decided - perhaps more than once - to change course in this respect, I'm curious to know what prompted your shift. Was it feedback someone close to you was good enough to offer? Was it adverse reactions from new people you met that persuaded you? Was it something you read or a conversation with others about this important skill? Was it watching others who struck you as being particularly inept - as I've often been - at making a good first impression?

Based on recent experiences, I'm considering iteration 6.0, first impression-wise, an average of a new one for each decade of my adult life. My latest tweak is not - as have been most of the changes that drove me to discard earlier iterations - being driven by an embarrassing incident or pleas from people close to me. I guess that's at least good news, right?
