Now this is cool! I stumbled upon a unique website today that allows you to email yourself in the future. Just visit http://www.futureme.org/ to send your future self an email to be delivered on your specified date in the future. You can write whatever you want, then choose the date that you want to receive it. Clear up to the year 2037!
I mostly just wrote about how life is today, and the hopes I have for the future. Then I emailed it to myself on my birthday in 2014. How cool would it be to create emails for your child to read at a later date? You could really be creative with this. Go check it out and let me know what you think.
