An emotionally intelligent person, concerned with effectively communicating with others, is interested in people’s reactions and takes them into consideration.  

What is clear to the person speaking, or writing, or pitching, or drawing, or singing, may not be clear to the people she is directing it to.  A person who would communicate well must be attuned to intelligent comments, as well as cluelessness, and the opinions of people who may be saying what they are out of an undigested mixture of helpfulness, envy, anger, confusion, ambivalence, distraction and so forth.  Many of these comments will be useful in helping to refine communication.

Even those who blurt out, ten seconds into a thirty second rough sketch, why the thing fails as a whole, may have a good point.  The only thing, it is sometimes hard, even for the person who graciously accepts suggestions and easily revises accordingly, not to snarl when this helpful approach is the only approach encountered.
