As I tell my friends, look out for what you do. This world is vicious. You let the wrong person in and they will crumble you into little pieces, you will feel so insignificant that you minus will become dust. Success isn't for idiots. One wrong move and someone can end up with your life in their hands, complete control over you. Use intelligence in all that you do. There will always be someone watching you. This is not paranoia, this is called life.
