Cicero said that gratitude is the parent of all other virtues. And it's true! A sense of gratitude can't combat feelings of anxiety, depression, anger and hostility, and even boredom. We - us, here - are constantly thanking our lucky stars for what we have and what we have to spread around. But it takes practice, and that's what we're talking about. It's amazing what you can learn about someone just by talking to them.
