I printed the goal sheet out and posted it on my refrigerator, marking it each day accordingly. Having this calendar on the fridge has prevented me from eating a handful of M&M's or bowl of ice cream on more than one occasion and it got me to the gym on days when I would have found an excuse not to go.
I look forward to days I can eat a sweet treat (or two or three) but I am now able to keep myself off the sugar on days I'm not allowed. And I'm finding an increase in what I do at the gym as well.
Adjustments for February weren't huge - but I increased the challenges a bit more.
