How to make multiple posts on Facebook COMPLETELY private?

[Bryanda]

I've had a Facebook since 2007, back when I was 14 and said/did some very dumb, very immature things. Things I would rather erase of my Facebook, which I now use more for classmates, family and coworkers, than to show off all of the "amazing" parties I go to. I want to make EVERYTHING from 07-10 COMPLETELY private. I've limited all of those posts to my friends, but I want to limit them to "Only Me." Is there a way of doing this without going through every single embarrassing, cringe-worthy post?

You have to go back and make each private for "only me" to view the post, or have a new fb and just make the old one private for friends and have the other for work and family
