As someone who can have difficulty socializing (unless it's something I'm passionate or knowledgeable about, but then i risk oversharing), i decided to try reading a book i ran into called Supercommunicators. It actually touches on a number of things you mentioned here, just curious if you happen to have read it yourself... It's been pretty enlightening for me, and i find the things I've picked up from it can easily be applied to daily life. Some good food for thought, at very least!
