Think positive about others even the ones you don't really know even if they're a bit weird. One time I was thinking bad about this guy I used to go to school with and even persuaded myself that he was bad. I ended up hurting him and got in trouble. If you're near someone that you don't really know and think that their weird because of what others said of them try to get to know that person because maybe they're really nice. Don't let your assumptions stop you from getting to know someone. Maybe what people said about that person is true but most of the time they're just lies. Don't spread lies about people either even if they're mean think of them in a positive way. That's what I try to do. Sometimes it works but most of the time it doesn't but there is nothing stopping you from thinking positive.
