This 2009 study suggests that introversion, corrected, can lessen our depression. Fascinating stuff. How much is our introversion in the way, is the question. A little or a lot? Hmmm. It's all relative, I think. And raises the opposing question of how happy do you want to be? Is it worth altering your basic personality to achieve nirvana? For some seriously depressed people, I suspect that it is. I have only empathy and I'll pass no judgment on them. For the rest of us, I guess we'll have to weigh how much it's worth.
