Oversharing depletes your natural secret reserves

A friend linked to postsecret, which is an art project that invites people to send in a postcard "reveal[ing] anything, as long as it is true and you have never shared it with anyone before."

It's a powerful idea, in that grassroots college-art way, and well worth looking at. It also brought home the realization that I have no secrets. There is nothing I know about myself that I have not told someone. I have things I tell some people and not others; I might have things I downplay or exaggerate; and I often suspect that even when I tell the truth about some things people don't believe me. But I have no absolute secrets.

I'm not sure how I feel about that.
