I think "starting over" is a concept that we need to get rid of. There is no starting over, there's just moving on. So do you really want to postpone getting on with your life (the life you're trying to build for yourself), or do you want to wallow in your mistakes for a while. Maybe make a few more whoppers to dig that hole just a little deeper before you start climbing out.
Doesn't sound so great when you put it that way, does it? It's become "traditional" to binge before a diet. It's also traditional to believe that dieting must be done perfectly, and if you make a mistake (no matter how small) why that means "you blew it" and the appropriate response is to eat like a maniac until you can "start fresh" being perfect tomorrow morning. Unless of course your mistake happens on a Thursday or Friday - then you have permission to gorge all weekend and "start fresh" on Monday.
It's an unwritten game we're taught to play, and we follow the rules without questioning them, because it's just the way dieting "is done" in our culture. Problem is it's a game that doesn't work - no one wins it, except by refusing to play by "the rules" we've all been handed.
To win, you have to break the rules. You have to make new ones, ones that will get you where you want to be, and "blowing it," then bingeing and "starting fresh" those are all the "old rules" the ones that don't work.
Every mouthful is a choice that can help or hurt you - so which is your next mouthful going to do. Is it going to get you closer to your goal, or move it further away.
I titled my 3FC Blog "Starting Over, Take 1847," and I regret it, because I learned (shortly after creating the blog) that there is no starting over. I've been dieting since I was 5 years old, I'm 44 years old now, and I realized that the concept of "starting over" has been my biggest obstacle. If I had understood from the beginning that even "failing" isn't starting over, IF you learn from the mistakes instead of deciding to mess up even more and start fresh tomorrow. It usually isn't the days honest mistakes that set you back it's the "might as well stuff my face all night so I can get it out of my system and start fresh tomorrow."
When there is no starting over, just moving on, you ask yourself which direction do you want to go backwards or forwards.
I constantly use the climbing analogy. If you're rock climbing and you slip and fall - do you keep climbing or do you throw yourself to the bottom of the canyon, so that you can "start over?"
The choice is obvious and yet it's not the choice we're "taught" to make. We're taught to throw ourselves to the bottom of the canyon - you can see why so few people ever make it to the top. Break the rules so you can get where you want to be.
