I have read several books on social skills and in the past few years I would say my skills are getting better and better by the days, after Covid my social skills were shot and it took me some time to get them back to basic levels.
The one issue with social skills is that the author doesnt know what your level is so they go based off theirs which is fine but in some cases it may be higher level than yours. Here's my review of these social skill books:
How to Win Friends and influence people - A decent book on social skills but every single chapter is basically be a nice person and let others talk while being a doormat in most cases. Not saying its a bad book but it covers just a few niche areas of social skills and thats it.
The social skills Guidebook - Pretty good imo, talks about many different real world cases, what to do in them, analysis in these case and different ideas that can be acted on it, also has a section with people for autism which is also very good.
The art of Witty banter - Very good book, you need to have a decent level of social skills, maybe after reading the book above to get a good grasp on witty talk but overall very good in descriptions, examples and real world cases.
With these books I have gotten better at public speaking, body language and making friends as well. I am still reading more books on this skill as I want to get the best at it, currently I am reading the Charisma Myth. #relationships source
