Have you found yourself doing something and thinking, Why do I keep doing this? We all have an unhealthy habit - or two, or three. Yours may be as simple as wasting time on the Internet, constantly checking your email, or spending too much time in front of the TV. Or it may be more serious, like habitual drinking, emotional overeating, constant self-criticism, or chronic worrying. Whatever your harmful habit is - you have the power to break it.
