What to read after Body Language: How to Master the Art of Nonverbal Communication with People (Gain the Unfair Advantage of Persuasion and Read People's Minds in Business)?

Body language and nonverbal communication account for roughly 55% of what we 

communicate. 38% of what we communicate is related to our tonality, and ONLY 

SEVEN percent is related to WHAT WE ACTUALLY SAY. This makes

a lot of sense, if we say "I'm so happy", but our body is slouched, and we 

say it in a sad tonality, NOBODY will believe it. Likewise, if we say, "I'm 

so sad", but shout it out like we're excited and happy, we are going to 

interpret the person as lying or actually feeling happy inside. Body language 

and tonality matters.

Although there are certain gestures that have been declared universal (have a 

common meaning throughout the world), most gestures mean different things in 

different cultures, regions, nations and even cities across the world. A 

certain gesture might mean something good in a certain part of the world but 

in another, it could be nasty or even an insult. Therefore, before using a 

gesture one is used to in their own culture, they should first find out the 

message they would be conveying when they intend to visit another region with 

a different culture. Otherwise, someone might just break their nose when all 

they want to do is to tell them how good they look.
