Life can be a rat-race. But if you start really looking at the people in your world, people who you've always just let pass by as bit-parts or background props in the movie that is your life, you might change your whole attitude on how you act and react to people. And who knows, it could have a dramatic impact on your happiness.
I hope you have the time to watch it even just once.
