Many of us understand this simple truth. Yet, we have a hard time remembering to use it. For example, when I have high pain days I tend to be down and grumpy, forgetting that I still have much to be grateful for.
So, remember, we have a choice to be grateful and happy for another day. God has blessed us, so why not share the blessings with others? A simple smile can make a grumpy person into a happier one. In turn, they pay it forward.
