As part of a Dear World project [1], Boston Marathon bombing survivors shared their touching, inspiring, and heartbreaking stories. And in an incredibly moving video [2] for the project, they also delivered a message to the world, saying:

"Dear World, we've been thinking a lot about time. How it speeds up and how it slows down. How it can slip through your fingers. Time can heal wounds. It can carry you across a finish line or strip away everything you love. But with every moment, we have choices — choices to put one foot in front of the other."
