This document discusses common communication barriers: static, lack of enthusiasm, distracting gestures, lack of focus, and verbal static. Static is created when what you say does not match how you say it, like having a monotone voice while saying you're excited. Other barriers include not showing passion through facial expressions, gesturing too much or repetitively, saying unnecessary information, and using filler words like "um" and "like". The conclusion states that communicating well requires constant learning and mastery of complex skills.
