What do you wish you knew when you were 16? What do you hope you remember when you’re 80? Your body has changed, your age has changed, your thoughts and beliefs have evolved. Amongst all this change, what has stayed the same? What do you hope always will? What piece of advice would you like to share with a younger generation? An older one? This is the place to tell yourself in a letter all the things you’ve learned and all the things you will never forget, your fears, your hopes, your advice, and your questions. Share it with yourself, with us, with the world.
