You can't be everybody's friend, you can't save the world, I learned this word: self-preservation. Once you do that, you can be friends with people, but how would you be a friend to anybody if you're not a friend to yourself.
Mike TysonDiscipline makes hard men. Every hard man is capable of being a killer. But every killer is not capable of being a hard man. They can't endure that much. It's all about the endurance. That's why they become killers. Because they can't endure the pain. They need to kill the pain to stop it.
