The stress control I've been teaching for over 30 years is taken from the philosophy and work of Dr. Albert Ellis, one of the foremost psychologists of the 20th century, whose programs are respected and taught around the world. In addition to attending, studying and teaching his work, I was also trained by him personally. He wrote the introduction to a book I authored titled "Living Thin, An Attitude Not A Diet."
The essence of his philosophy can be expressed in one sentence: "It isn't what happens or what they said or did that upsets you, it's your point of view." What you choose to tell yourself is the key to your being upset. Dr. Ellis tells us that most of us are born with a natural tendency to fall apart whenever life rains on our parade. The good news is that we can actually train ourselves to think in a positive fashion. The payoffs from overcoming all or nothing thinking in all areas of our lives are overwhelming.
You need to begin talking to yourself as if you were your own best friend rather than your own worst enemy. Example: The enemy within you, "When I overeat after swearing I would not, It proves I will always fail and that I simply don't have what it takes." Your own best friend would say, "So I overate. It's not the first time, and probably won't be the last time. I've been doing it a long time, but guess what? I refuse to give up on myself. I'm determined to take care of the only body I'll ever have. I refuse to live as a victim."
