In the final episode of a season all about help, Meredith sits down with students from the writing and publishing organization 826 Boston, which just released a new book — called  “What if the World Needs You?”— that’s full of advice and life lessons for young people. Also, Meredith’s producers surprise her with a collection of stories from her friends and loved ones about times she has helped them in ways large and small. Email us at loveletters@boston.com.
