It's not the end of the world, though.
Sometimes having a piece of cake is important, I think. Without that piece of cake or piece of candy or whatever you are craving, you defeat yourself. You tell yourself so many times that you can't have something and you deny yourself and deny yourself and when you do "cave in" you beat yourself up. At least I know I do.
I could have denied myself the piece of cake today. I could have disappointed my granddaughter by not having a piece of cake for her third birthday, but instead, I had a small piece instead of the massive piece I would usually have. Also, I limited some other things I ate during the day, so having the piece of cake was okay, in my opinion.
Don't always deny yourself. Granted, in my case, I have to be careful about sweets because I am diabetic, but on occasion, I think a piece of cake is good for everyone!
Until tomorrow, don't beat yourself up for a piece of cake or a piece of candy.
