INTJ here as well. Funny thing, I decided to step out of my shell and sign up for a volunteering job providing my sales, marketing, and admin expertise to a prominent Christian charity in our area. Talked to the head honcho a couple of months ago, who was eager to have me jump aboard. Now, obviously, all that has changed and all plans have been put on hold. Is it sad that I'm relieved? LOL Probably. But I'm content being a homebody. Give me a pair of earbuds, a good audiobook, and my garden and I could ride this thing out for years with no regrets.
It's hard to balance that Christian "shining your light" thing with an INTJ personality. I'm always a work in progress...
