There is a difference

Self-esteem and self-image are not the same thing. Your image is what you are projecting to others...what you want them to think, while self esteem is how you feel about yourself. Two points of reference.

How you convey these things can be body-language or more likely verbal. If you are what you eat...you are also judged by what and how you say it. For instance, I might think I am well read. Your perception could be that I am sententious, pompous or priggish. Two views and I chose the words...carefully. 

An elementary example; some extremely good words are ignored when a curse word will take its place. If I use these terms in a description, I am not automatically adorned with the terms; oafish, boorish, churlish, loutish. Conversely, if you call someone "a f---n' a-----hole" you have told everyone exactly how you perceive yourself!

Just Sayin"!
