I’m also introverted, and I also found this article overwhelming – if I tried to do it all at once, which seems so laughably unrealistic for me that I just wouldn’t try. Instead, probably the best way to read this is as something to approach gradually. Try just one thing on the list, or two if you’re feeling ambitious. Go for a delta that you can manage. And see if it’s working for you, because often the advice that works wonders for one person completely falls flat for another.

(On a slightly funny personal note, the thing that helped me most with social skills was watching the first few seasons of Buffy the Vampire Slayer in my first year of college. The actors emoted so clearly that even I could understand what feelings they were trying to convey, and that’s how I learned to do body language and appropriate vocal tones. This took me from unapproachable to merely awkward, a huge step up in the world.)
