A little "Diet" humor
Recently I strapped on a step counter and went for a walk with my Mother.
"What's that?" she asked.
"An exercise tool that keeps track of your steps," I said. "I'm hoping it'll help me lose weight."
Clearly unconvinced, she asked, "Wouldn't it work better if it counted your bites?"
It's not that some people have willpower and some don't. It's that some people are ready to change and others are not.
