Life is different for everybody and the way we live our lives is the same. Some people get to live good lives, some really bad but then there are the people who get to live both sides and it is hard to deal with along with the people who live bad lives aswell. Our past shapes a small percentage of who we are today but who we hang around and our actions defines who we are today. If you hang in the wrong crowds then you will become a different person than if you were to hang around in the perfect crowd. There may not be such a thing as a "perfect crowd" but if you love your life and don't want anything to change then you know you have mixed into the right crowd. When the people you hang around try to change you then you know you are with the wrong crowd and you should move in and find those people who will love you for who you are and those are the people you can trust with your life.
