Think of yourself at a key point in your life as a learner. Maybe it was 5 or 7 or 18 or 25 (or heck, you might be experienced enough to use 50!) when you were just starting to figure things out in the world.
Write yourself a letter with advice from what you have learned since then. What information, suggestions, ideas would have helped you then if you had a message from the future? (hint, this would be a good thing to publish on your blog and post the link here)
