Love it, it sets the mood for the day !!!
I have seen this saying for a lot of years and now I am happy as **** that I have it on a cup! It is outstanding!
My former boss, now the Deputy Director for a State Environmental Protection Agency used to have a cartoon of a WWII or Korean War solder with a canteen cup with the saying above his head. I just thought a set of cups was the perfect gift. He loved them!
