Must be realistic

Today is my birthday and I wanted to be able to buy a few new clothes. And of course I had an unrealistic goal that I would lose 20 lbs by now. So, since I haven’t lost the 20 lbs I’d planned to punish myself and not buy new clothes.
Well, I have learned that it is important to make goals realistic so therefore, even though I am not necessarily buying clothes in the size I want. I will still buy a new outfit to celebrate what I have accomplished.
I want to be a realist and not set impossible goals that set me up for failure, so what I have started doing is: while keeping my food journal at the beginning of each week I set one-two goals that I will work on for the week!! This is only my second week so will see how it goes.
