Hannah Brencher: Love letters to strangers

Hannah Brencher's mother always wrote her letters. So when she felt herself bottom into depression after college, she did what felt natural -- she wrote love letters and left them for strangers to find. The act has become a global initiative, The World Needs More Love Letters, which rushes handwritten letters to those in need of a boost.
Hannah Brencher believes in the power of pen and paper, and has started a global initiative that encourages strangers to exchange love letters
