Do you know what skill(s) you need in order to keep to your dieting regimen? Yes, skill. For that's what it takes to override your impulse to violate your dieting regimen. That's what it takes to regulate the emotions that turn you toward food. That's what it takes to build up your tolerance so you can endure the distresses of dieting. Skill is what it takes to not do what a friend does when she eats too much, too often, or eats all the wrong foods. It also may take developing new skills to handle the stress and strain of your everyday life.
Get the point?
So what skills should you have to keep you on your dieting regimen?
You'll have to make an analysis of the skills you have and those that you don't have (or don't have the way you really need them to be). Once you make the analysis of what's there and what's missing, go over the two lists and rank the items in each list. In the "what's there" list, rank what has been serving you the best as #1, and so on. In the "what's missing" list, rank what you think is the most important thing you're missing as #1, and so on.
Next, take a look at what you've ranked in the "what's missing" list and see where you can get started developing that skill. You don't have to start with the most important skill you're missing. That might be too hard. Start where you're comfortable, even if it's the last item on the list.
And there you have it--your own skills lists, in your own words.
