Gretchen Rubin is one of today’s most influential and thought-provoking observers of happiness and human nature. She’s the author of many bestselling books, including The Happiness Project. She discusses happiness and good habits with her sister on her podcast, Happier with Gretchen Rubin, and helps people track their happiness-boosting habits with her award-winning app, Happier.

Each year on the podcast, she and her sister suggest the annual challenge to give themselves and listeners a practical, manageable way to boost happiness and build habits that year.

This year, the challenge is “Write 24 in 2024.” Write for 2 to 4 minutes— or for 24 minutes— every day in 2024.

For the month of April, she is teaming up with Paper Source to focus on letter writing. To learn more about Happier and get letter writing prompts in your inbox every day this month, visit
