Black friends
This is not art related per se, but it is pop-culture and definitely American culture. I've spent most of my life being around an incredibly diverse group of friends. Recently I realized that through career choices, moving cross country and my personal interests that my group of friends is not nearly as diverse as it once was. I think it's VERY important to have a diverse group of people around you at all times from different ages, races, sexual orientations and the like. It keeps you from becoming boxed in mentally, culturally and socially. Fear not that which is different because it allows you to see who you are and evaluate whether you want to stay who you are or try something different. If who you are is right for you and you're secure in it you wont change, but will have gained a new perspective on yourself and your choices.
