There is a site called FutureMe, on which you can send an email at a future date. Some of the emails are public and this one sucked me in. I like the format. Personal essay with a smattering of mediore poetry and a couple of spiritual debates for good measure. Seems like something I'd probably write, actually.
I like the idea of sending yourself something from the future. I think I'll send all of you my secrets, to be read 5 years from now. I'm not sure if I'll be around 5 years from now. If I am, I will be considered a "longtime survivor".
