HAHA! I just read your comment, "...never giving in is the beacon to strive for," as "...never giving in is the BACON to strive for."
It's a daily effort, for sure. And like Vince Lombardi said, “Perfection is not attainable. But if we chase perfection, we can catch excellence.”
I write down every thing I eat, every bite, every taste, everything. It helps me be accountable. It's easy and convenient to pretend I didn't eat a small piece of cheese, but my body doesn't pretend. If I eat enough small bites of stuff, it adds up quickly. But if I get in the habit of writing it down, my natural laziness becomes my ally. I'm not going to eat this piece of prosciutto because then I have to find a pen and get my notebook out and write it down. Too much effort.
