I have been a big fan of the postsecret project for years. Every Sunday I go to the website and I read the posted secrets. Often they are depressing, often they are incredibly beautiful, and every once in awhile, I find one that is down right cathartic.
Before I started reading Post Secret, I thought of "secrets" as events that you don't want anyone else to know about, like "I killed a man in Reno", that sort of thing. Now, I think of secrets as things I feel about myself and the world that are hard to express. The truth is, I am as secretive as anyone else, and so are you.
This little video is sort of intense, but it nicely explains the project, and I really like it.
