First Negative and positive behavior change from person to person. one thing you consider as positive may not be positive for some other person. it depends on your own perception of the situation or event. good and bad, beauty and ugly, good taste and bad taste (some people love දුරියන් and others hate දුරියන්, but yet the stimuli of chemicals in දුරියන් is still the same, some hate, some love it)
some people like to be funny, some people like to look wise, some don't care the shit..
and in the corporate level (as far as i am aware of,) people are not looking for brand names such as BMW,(they incorporate with self image, which is a whole different thing than personality, if there is any) but they looking for give away tells, like drumming of fingers, their tongue says "yes" but body says "no". crossing their legs, crossing of arms. micro facial movements. even a Judge in the court is aware of this true signals. A judge is well aware of the fox inside the gentleman look.
behavior can only be changed by changing the attitude itself. (since my job is hypnotherapy, i change the attitude of a person on a particular subject, event, or feeling)
and i agree with you that i copied the definition from google.
