If you could write a letter to your future self, what would it say?
We asked young people to do just that. Everyone's letters covered a different set of priorities. One hoped to be a millionaire, another urged her future self to hit the gym harder. Their answers ranged from organizing their closets to standing up to the school bully.
But then we wondered how their future counterparts might respond. What advice would older folks give these kids? And, more importantly, what is the one thing in life the kids simply can't forget to do?
Watch the video to hear what "the future" had to say.
