Can you measure gratitude?

Last night during our new years celebrations the resolution question came up. Most people wanted to do something like run four times a week or quit smoking…. All very admirable, I just wanted to be more grateful. They retorted, “you can’t measure grateful!” I replied, sure you can, “At the end of every day I’ll ask myself if I was more grateful and gracious in my actions, and if I was I’ll give myself a check for a grateful day. At the end of the year I’ll add up all the grateful days and see if I was more grateful.” All, but one, looked at me with furrow brow. I realized, all but one, didn’t get it. But I insisted that I will follow-up with their retort, can you measure gratitude? For myself it doesn’t matter if I measure it, but for the rationalists I must find the measure. Or maybe not, gratitude is something you must find for yourself…
