If you to improve your class for example, you have to presuade/convince other people to your idea. He mainly wanted to say changing one thing, can change you. I can use it in the future if I feel the need to make a better school. By telling others if you want a better school you need people to report bad things. No one should be bullied or tormented. School needs to be enjoyable, not looked at by a bullied student as a deathtrap.
