It's amazing what one word can do to your mood. My wonderful hubby has taken to calling me "Sunshine" in his emails & texts. Why? I don't know. You'll have to ask him. What I do know is that this has a profound effect on my mood.
Lately I've been struggling with pain & fatigue more than normal. So I've felt nothing like sunshine. But when he calls me that, I perk up. I smile a little more & I complain a little less. It changes my whole outlook on my day. He probably has no idea that just that one little word has made a difference in my moment, my day! So now he does ;-)
So think carefully about the words you use. You never know, they might change someone's day for the better or for the worse. Words have power!!
