There was once someone told me that, "change" itself can only occurred when there is a choice there, but seldom people were giving themselves the choice. Who restrict the choice? You? They? Or them? I believe everything that happened always have a cause behind. As long as we, ourselves are not restricted to ourselves, choices will always be there, and changes is just about the time factor.
Change, always the word that make people think. People love and hate him. It make people think in such a way is because it required courage and wisdom to perform the change! Nothing sound as simple as it look. Perhaps somehow, somewhere, someone will tell you that "i'm your change", then you have to consider whether you deserved the change or not!
