A few interesting articles have come out recently regarding introversion, including this interview on NPR. I had the chance to work with the Myers-Briggs personality test when I was in physical therapy school. I took the test, and it confirmed what I already suspected, that I was indeed an introvert. Many of today's work places are not designed with introverts in mind. My day job is in a wide open space with very little privacy. I think I cope with it just fine, but by the time I get home, all I want is to curl up in a corner by myself for a little while. Not easy to do with a toddler around. Impossible, in fact. The next best thing is hanging out in the backyard and letting him run around with the dogs while I decompress.
So I don't find it surprising that my major outlet is writing. It's solitary, requires silence (for me at least... I know some writers who need noise or music), and allows me to hang out in my head for a little while. Bliss! And I enjoy social media because it allows me to connect with people at my own pace.
It's been interesting watching my 2 year old develop. He's a bit like me in that it takes him a while to warm up to situations, and so I suspect he might be an introvert also. I wonder how he'll do in a school system that seems increasingly geared towards extroverts.
