Just looking at the Los Angeles sky line is motivation for me. This city can change your life in such a short amount of time. But you have to be the type of person that believes that they have the ability to be greater than their current situation. Its one of the last places where the American Dream is truly alive. Impossible is nothing in the city of angels.
Movies like Menace To Society and Boyz In The Hood only show one side of LA. You have to experience the city first hand. That's all I can tell you. There is something for everyone in LA.
Just make sure you don't walk down Crenshaw Blvd wearing the wrong color. Not a good look. Holla!
