I have been bad about "blowing it" sometimes. (I feel almost silly even saying that, since I am a huge repeat offender!) I will binge and/or run out of my points for the day very quickly. I tend to say "I will just start fresh tomorrow."
I am learning that, this state-of-mind tends to give me an excuse to stay OFF course.
This: "Well, I blew it today, might as well eat what I want the rest of the day."
Turns into this: "Well I messed up all day yesterday, so I will just eat bad the rest of the week and start again on Monday"
Sometimes that leads to this: "I messed up this whole week, I will just start next month."
Vicious cycle. Weight gained. Hard work, undone.
I now say this:
If you mess up, make sure the VERY NEXT THING you put in your mouth is on plan. Pick yourself right up and keep going that very day.
This is a hard lesson to learn, but a critical one for many folks.
