An arrogant person thinks they are better than others, while a confident person knows they are just as good as others. Confident people will rarely be found lecturing or preaching to others or how they are wrong. Furthermore, they usually show respect while listening to somebody. Arrogant people have difficulty listening to others. They often exude negative energy and blame others if things do not work out as expected.
Arrogance is usually the result of a defense mechanism used by subconscious mind in order to prevent further criticism. Confidence comes from positivity, optimism and mental steadiness.
Never never be arrogant.
