My signature: If you want something you've never had, you must do something you've never done.
In general, I try to think that there are people in worse situations than me. I once saw an episode of America's Next Top Model where all but one of the girls were crying, having tantrums etc and taking it too far. The other girl said 'some people have war in their country.' When people around me are stressing over the silliest things, making drama or I'm being stupid, I hear her say that in my head.
