Hey there! I am sort of doing the same thing. I have only been on SparkPeople since the beginning of June but I am having a hard time staying on track. On Friday Jul 13
I decided to rededicate myself to the process. Also like you, when I saw the topic, I thought "OK, THIS is something I can work with!"
When I decided on the 13th to re-start this whole process, I also decided that the only goals I could make at this point in my life was to make a goal at the end of each day to successfully make good nutritional choices the following day.
At the end of each day as I am finishing entering my food, I use the notes in that section to say what was good or bad about the day (e.g. right on target for calories, but to much fat for the day), then I reaffirm my goal for the next day. I ask myself is there anything special going on the next day that I need to prepare for (for example, tomorrow is my birthday, I'm being taken to lunch and to dinner and there will be cake at the office.). So now I know that I need to plan for how I am going to handle tomorrow so that when I have to make a decision, the decision is already made for me. For example, I know I am going to a greek restaurant tomorrow. I LOVE greek salads. So I'll get a salad and ask for the dressing on the side. When we have cake tomorrow, I will have a piece, but it will be a small peice. I know that I may go over tomorrow - but it is a special day. At the same time, I can also make wise choices and not overdo it.
When there isn't anything special going on, I just restate the fact that I can make good choices the next day. I think about what I will eat so that I can be prepared when it is time to make something and I consciously think about/write down that if something comes up, that I have learned good things from this site to help me make wise choices. And I leave it at that, until the next day.
Always believe in yourself first. There is no profitibilty in believing in anything OR anyone else if you can't have faith in yourself!
