Don't give the scale the power to make you feel shitty about yourself.
Don't give it the power to punish you after a day of glorious and delectable culinary pleasures.
Don't give it the power to justify a reward based on the number that it shows you.
THE SCALE HAS TOO MUCH POWER AS IT IS.
Take back the power from the scale. And if you struggle with doing that, then do yourself a favour and ditch the scale.
