Living in today's society will have you thinking gangs, drugs, and sex is cool. If you are into anything outside of that you are weird, socially awkward, or, God forbid, nerdy.
This is because there is a lack of representation in the media of people with darker skin tones doing things that are positive and motivational.
What you see around you has a strong impact on what you see in yourself. If you are only portrayed negatively in the media then subconsciously you will believe that all you are destined to be is negative.
