Couldn’t have said it any better myself. Enjoy.
“If you are searching for the common denominator in your life, you are in luck. You are it. Now that you know you are the only consistent factor in any situation, you can begin to figure out how you are contributing to your recurring challenges and problems. This is great news because, once you realize you are at least part of the problem, you can begin to change your behavior, beliefs and attitudes that are contributing to the situation. Keep in mind that you have to concern yourself only with you, not with any-one else. You are the only one you can change. So don’t focus outside yourself. Focus on the common denominator. You will be amazed at the difference this process will make in your life.”
