I pledged that I would take my lunch to work every day and not drink soda this week.
So far so good. Much better then last Monday, anyway, when I pledged no soda and an hour later was sipping on a fountain Pepsi. The near-traffic accident I was involved in helped me to justify my need for the sparkly beverage.
My decisions have nothing to do with wanting to be uber-healthy or uber-frugal. I just want to be healthier and frugalier then what I have been.
