Well, it’s the middle of a grueling work week and a kind soul brought in carrot cake. Yeah, it’s a good day. Maybe it was the cream cheese icing that did me in. Or the orange-speckled center. Or the fact that I was breakfast-less at 10:00 a.m. and needed a pick-me-up. Regardless, as I stood in the middle of our break room and savored the sugary deliciousness, I smiled. Not just a simper of content, no. This was a thorough, full blown “life is grand” type of smile.   I know what you are thinking. It’s only carrot cake, Olivia. That may be true. But does it matter? Do we really need to justify the little things in life that turn our frowns upside…
