We do not know how other people perceive us.
In the extremes, this can breed self-consciousness, or it can breed cockiness.
Neither warrants much praise.
Think about it.
Looks, in the abstract sense, will make a significant impact on a person’s outlook in life, more than they would like to admit.
If people truly perceive a person as looking great, then what harm is done?
This all diverts itself to the misconception that looks are shallow.
Ethics will teach us that beauty is only skin deep. All true, very true; but only to an extent.
“Looking great” and being beautiful are two separate ideas, as beauty is largely subjective.
However, looking great is a matter of culture and place.
