Maria Shriver on Instagram: "What if we all focused more on joy? What if we all focused more on how we could make other people happy? What if we made it our mission, not to be wealthy or to collect things or to do things just because, but instead focus on what truly matters? What if joy was the currency of life? How would that change your perception? Sit with that. Think on that. And then see if you too can go out into the world and give some joy away for free! #inspireheartsandminds"
