Of all of the personality traits I have attempted to change over the years, my introversion has remained the most stubborn. It's a shame, too. I can briefly emulate extraversion, at an enormous cost of mental energy and feel like a dog walking on its hind legs. Nor do I seem to be able to extract the purported benefits of it. And the list of approaches I have exhausted is, in retrospect, more than a little shocking. It's the one area where "fake it until you make it" seems to have failed me utterly.
