There's no committee that says, 'This is the type of person who can change the world - and you can't.' Realizing that anyone can do it is the first step. The next step is figuring out how you're going to do it.
Everybody has a responsibility for what they put out into the world. Rather than trying to figure out what other people should be doing, work on your own interactions in the world and whatever influence they have. All of it has an effect.
