Being worried weighs down the soul, having word encouragement heals a person up. I've encountered a young woman when I was depressed about certain issues. A little advise and next thing I know I'm smiling and drinking a free drink.
I'm at a coffee shop and just watched a woman come in and realize a wallet was left in the chair she was about to sit in. Without opening it or saying anything, she brought it to the counter and turned it in. I told her she was awesome for doing it and she simply said, "I shouldn't be awesome… just normal."
