What is “personality”?
According to Merriam-Webster, personality can be defined as a set of distinctive traits and characteristic or as the complex of characteristics that distinguishes an individual or a nation or group.
Your personality is how you present yourself to be. Each person has his own personality that sets him apart from others in a crowd, but why are some people more easily recognizable than others? The key here is the difference in visibility. People will more easily notice you if you project your personality and make it easily “accessible” and viewable by others.
