I'm all for mini goals! My first mini goal: go back to onederland. But I also have ongoing mini goals like sticking to the diet for one day, and then when that week is over to stick to the diet for another week, taking each day as a goal I achieved. If I don't take things like this, slowly, daily, I get very anxious and frustrated because as you said, the scale doesn't move as fast as I wish.
I have come to realize that when we are not dieting we have instant gratification for everything. I want candy, I get candy. I want a soda, I get a soda. I'm craving chocolate, I get a chocolate. But with dieting there is none of that, and there is no instant gratification. Taking my weight loss day by day, as an ongoing series of mini goals to where I lose these few lbs and get back into the 100s, and then go from there, also on a slow day by day basis, is the only way for me to succeed at this. That being said, this is the first time I ever took a diet this patiently and meticulously. I have failed at all my other diets because I get too impatient to reach my ultimate goal.
I hope my two cents help you, since we kind of seem to be on the same boat about this! Make a smaller ticker for shorter-term goals. Good luck!
