Is charisma something you are born with or something you learn through your life experiences? Why are some people so good with it and others socially retarded?
I mean look at Anna delvey, she was able to get away with a shit ton of things based on her charisma https://youtu.be/YXu289P-dD4

Also do you have any charisma tips or books that you personally find useful?
