One of my favorite songs, "Ooh La La," goes, "I wish that I knew what I know now, when I was younger." Well with FutureMe.org , you can at least remind yourself then what you know now. This website lets you write an email to yourself and set it to send in the future, 1, 5, 10 years later —whenever Future Your wants to hear from Old You.
Seems pretty basic, but there's also another fun feature on the site: "View Public Entries," which is exactly what it sounds like.
Don't worry, you can set your entry to private so it's not public if you don't want it to be, but thank you to those who do! Especially this guy  — who is congratulating his future self on getting girls despite his present setbacks. It definitely made me giggle and warmed my heart all at the same time.
