When Hannah Brencher was going through depression, she wrote encouraging letters and left them for strangers wherever she went in New York City. It was her way of paying back the love letters her mother consistently left for her. Then she wrote a blog post with the offer “If you need a love letter, just ask.” Nearly four hundred handwritten letters later, the idea for The World Needs More Love Letters was born. To date, the nonprofit has delivered more than 250,000 love letters to people in seventy-three countries. You can nominate people who you think could use love letters. The organization chooses new recipients each month, and site visitors choose which ones to write to. The letters are sent to the nominators, who read them to make sure they’re appropriate before giving them to the recipients.
