the world can't change us only the people in it

I think both are right. Sometimes we did something wrong or right to have an effect on the world.But we were also changed by the world where successful people encouraged us to chase after our dreams.

Who can tell me that it is the world that changed us or it is we that changed the world ? I think it's depending on the people, because people who just followers(not like twitter I mean) will be changed by world, and people who followed by followers (such as trendsetter) will change the world.. hehe ^^
