I'm So Doing This When I Have Children

Yes! Love this idea

Been wanting to do this ever since I could remember!

Oh this reminds me of this site called DearFutureMe, where you can send your future self emails and set a timer, so like 2 years from now I'll receive it. It's really cool to see how you've changed

And reserve them a good instagram user id too

This is an awesome idea but I highly don’t any 18yr/old is going to have the patience to sit down and go through 18yrs worth of emails.

Just in case you don't think we're tech-dependent enough.

This won't work, because if your email address isn't active (sending email or opening email, not just receiving it) then it will get deactivated after a couple of years.
