Write letters to your future selves — open in 5 years

How to do it

Week 1: each of you writes a letter to your future self, five years from today. What do you want to remember about right now? What questions will you have? What do you want to ask. Week 2-3: revise. Week 4: seal them, put them in a small box. Set a calendar reminder for exactly five years out. Forget about them. The day comes, you open them. Cry openly. Both of you.
