When I was younger I used to write letters to myself for the future. I'd hide them somewhere and then completely forget about them and find them years later. It was always so entertaining to read about what was important-and the questions I would ask my future self. Sometimes I put specific timelines with them 'do not open until you're 16' etc. Anyway - Free People's blog featured this site FutureMe. You can write yourself an email and then pick a date to have it sent to yourself (up until the year 2037). I love it!
