Gratitude or giving thanks is the practice of paying attention to the moments, instances, and experiences of realizing all that we have and all that we are is a gift from God. Ideally we would be in a state of gratitude every moment of every day! However, my experience is that it takes a lot of effort on my part to really stop, recognize, name and give thanks for those things that surround me each and every day.
This is probably not the first, nor last time that someone might suggest to you to stretch yourself and spend a few minutes each day to reflect on your day and write down or mentally tally all the moments for which you are thankful. Perhaps, this might be the time that you make a choice and take up the practice. I will tell you, it is worth those few minutes.
