Whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
Just let a smile be your umbrella, On a rainy, rainy day . . .
I believe that the idea of having a positive attitude is an idea that God thought up and it's good advice. Did you know that if you grin, it acually changes the way you feel inside? Did you know that laughter is healing? Ever heard that old song about accentuating the positive and eliminating the negative? Could it be that God inspired that song? God is very positive, very optimistic, and very cheer-ful.
