International Women’s Day is coming up on March 8. Today, YouTube launched a #DearMe campaign to celebrate woman, and encourage video creators to support teenage girls. The initiative asks women to tell their subscribers the answer to the question: “If you could go back in time, what wisdom would you share with your teenage self?”

YouTube like Hannah Hart, Lily Singh and Michelle Phan have shared their words and YouTube even put together a video to explain the kind of messages #DearMe strives to use to empower young women. YouTube is asking YouTubers all around the world to upload video letters to their younger selves, providing advice and encouragement they wish they’d heard earlier in their lives. You can also participate in the campaign by using the hashtag #DearMe on social media, or making a GIF through YouTube’s Tumblr page.
