One of my all-time favorite websites is postsecret.com.  Try it once, and you'll be hooked.

I don't know what it is about reading other people's secrets, but it's like therapy for me.  It helps me realize that some of my secrets aren't as bad as I thought.  It helps me feel like somewhere in the world someone else thinks the same things I do.  New secrets are posted every Sunday, but it's my Monday morning ritual to go through the new secrets every week.

There are also a few books that founder/author Frank Warren has compiled from all the secrets that get mailed to his address in Germantown, Maryland every day.

I have yet to send my own secret in, but I will someday.  I ask myself each week which one I'd be willing to part with, but haven't found that answer yet.

Anyway, there will be a new app coming soon to make submitting your secrets even easier.  Check it out:
