Hey guys, as the title says, I'm looking for concise books that can help me improve my social skils.

I find myself as an 'error and trial' guy so everything I see or read I test it on the field first on the first occasion.

I find communication as an underrated skill that needs to be in spotlight more and more.

I have read many books and ugraded my social game on a decent level but always open for good quality suggestions.

Cheers and thank you in advance!
