Never judge a book by its cover
Meeting people may sometimes be exciting, you get the chance to see different attitudes and see things from a new perspective.
Although the process may be entertaining, we tend to underestimate the person by what we see based on their appearance.
It mostly depends on our first impression of them which shows us their capabilities.
Overlooking a person occurs when we do this and there is a high chance of a potential is being lost this way.
A simple way to start by finding the potential you may have overlooked is by starting to look around yourself first.
