Change is the only certainty in life. People change, just certain aspects of their personality never seem to. It makes for stagnation.

I am a strong believer that you can be whatever you put your mind to, But there are things in life that will never change. I think of it more as growth than change. You can not choose your family, You can not choose your country of origin, You can not choose the time you were born. You can grow into a family you build, But you can not change into a different family. I think this gets into the fate/destiny conversation. You can fail and change or you can succeed and grow.
