There is no way to measure the loss opportunities caused by lack of self discipline in your life. Your inability to control your weight might seem like just a long term health issue, but it might have also thrown off life partners that might otherwise have been interested. Your lack of control over spending might seem like just a way to get into credit card debt, but it might also be the reason for increased weight gain and tensions with your spouse.
Understanding that you have no control at this moment over your impulses is the first step. Once you accept this fact you are ready to tackle them with the advanced techniques in this book. Understand that you will need to be stern with yourself when you get into situations where these demons are likely to emerge. These can be times when you are going to eat a second or third helping of food. They can be all those times when you know you should start working, but you put it off to do something more interesting - like talking with a colleague.
Get your life organized with principles of self-discipline that will serve you forever. When you start focusing on some areas of your life, you will notice that it improves other unrelated areas in your life.
